Any PDF file I open with trunk builds returns a blank page and no plug-in
interface.  If a click around the Acrobat toolbar buttons sometime appear or
some parts of the interface, but the document pages still blank.

BTW I have the same problem under 9.1. Can you reproduce this under 9.1?

hmm, we have not had any other reported cases of that on 9.1, or at least we are
unaware of that. I am reopening this bug to ensure this gets tested under 9.1 by
our QA.

Bejamin: what version of Acrobat are you using?

Shrir: can you please check this out under 9.1?

oh, also Bejamin were you using a mozilla nightly trunk build or a mozilla
nightly branch build, or a Netscape branded branch build? And can you please
tell us what the date is of the build?

I'm confirming this bug. I totally see the problem as described in the first

I wonder when this regression popped up? Is it reproduceable in RC1 or 0.9.9?

I was the reporter for bug 156126 which has now been marked as a duplicate of
155708. The description of bug 155708 is exactly the same as what I am seeing [
in bug 156126] with the particular combination of Mac OS 9.2.2 US & Acrobat
Plug-in 5.0.5 with numerous successive nightly builds of Mozilla 1.1 including
today's Build ID 2002071808. The details given in bug 156126 include attachments
of a screenshot and a stdlog file. This bug never occurs with numerous
successive nightly builds of Mozilla 1.0.0 nor with the current 1.0.1 versions.

This bug makes Mozilla 1.1 completely useless as a browser for readers of
scientical & technical journals which are nowadays commonly published as full
text online, as PDF files of each journal paper, in parallel to the printed

Mac G3, OS 9.2.2.

Using trunk build 2002071808 and Classic theme, I was able to read PDF files. 
But I then downloaded, installed and selected the 'Little Mozilla' theme,
decided I did not like it and went back to the 'Classic' theme (each time, of
course, shutting down and restarting Mozilla).  I then found that I could no
longer read the PDF files.  After I had closed down and restarted my computer, I
could once again read the PDF files.

Computer: Mac G3.  OS 9.2.2.  Mozilla Build: 2002072308 (trunk).

I can view PDF files in Mozilla, but I cannot download and save anything that
will subsequently display the PDF file.  In Netscape 4.79, saving as 'Source'
produces a file that Acrobat Reader 5.0 opens and displays complete.  In
Mozilla, saving page as 'Complete' produces a Mozilla file and a folder full of
other files;  saving as 'HTML only' produces only the Mozilla file.  But opening
in Acrobat Reader will show either a blank page or just the first screen of the
PDF file.

And yet one more comment.  I tried saving the PDF file as xxx.pdf instead of
xxx.html.  That resulted in a file with the Acrobat icon, but it still couldn't
be opened.

I have now gathered more information.

1. VIEWING PDF FILES: When opening a pdf file (e.g. on
it appears with its upper portion whited-out.  If the screen display is scrolled
right down and then up again, the pdf file appears complete.

2. INABILITY TO SAVE PDF FILES: This turns out to be site-specific.  The
behaviour I described in my earlier addition to this bug report occurred on
which is a password-protected 'View bills online' site. On other sites, e.g. the
one given under 1. above, the pdf file can be saved satisfactorily.

Screenshot of PDF displayed on Moz1.1b but lacking Acrobat controls

notice that the ususal Acrobat iconic controls [e.g. floppy symbol, printer
symbol etc] do NOT appear immediately above the top left corner of the PDF
display sub-window, as they should do. Above this can be seen the PPP connect
symbol and that the current theme is Little Mozilla 1.1.

I confirm the additional comment # 17 and #18 from Michael Graubart. The scroll
down and then up again 'work around' works AOK everytime. This seems to imply
that this drawing bug might have a trivial remedy---especially as it does not
affect either Mozilla 1.0.0 nor 1.0.1.

I have repeated this separately with both the 'Modern' and 'Little Mozilla 1.1'
themes enabled.

In addition, I was able to print the displayed PDF file
<http://bmj.com/cgi/reprint/325/7357/176> but only if I used the Print... option
of the File menu. If I tried the Command + P shortcut nothing happened. If I
tried to Preview the printing only the 1st Mozilla preview progress bar appeared
but no preview window was actually drawn.

In addition, I was able save a valid pdf file from the The Lancet site---only by
using the Save Page As... option off the File menu.

After the failed attempt to print or save the generated pdf file on the OneTel
site my system was left in an unstable state & Acrobat Reader froze.

Comment 21

The plot thickens ...

Try this URL
after you applied Graubart's "scroll down all the way & then scroll back up all
the way" work around, after the document is "Done".

In this case, the Acrobat Reader is drawn completely normally, after doing the
work around, so maybe the HTML code has something to do with the bug as this was
a direct link to the PDF file rather than to a page from which it can be
downloaded by then selecting a link.

Mac G3 (old beige) - OS 9.2.2 (International English) - Classic theme.

When I clicked on the link in A. Wight's message, Acrobat Reader opened but the
screen was blank and had no scroll bar so that I could not apply the 'Graubart
workaround'.  By clicking on Acrobat reader in the Application menu, I could
bring up the Acrobat tool-bar, but still no text on screen.

When I quitted from Acrobat and copied and pasted the URL into the Navigator
location bar and opened, Acrobat again started, but this time a bit of an image
and the scroll bar appeared, so that I was able to apply the 'Graubart
workaround'.  Then the full document became completely readable. So this site
did not really work any differently from the others that have been tried in this
context.  It is not clear to me what has been found to be different on this site.

Scrteen appearance after activating link in e-mail and then scrolling down and up

This is what the screen looks like after activating the link to the site in an
e-mail, then scrolling down and up and scrolling down a little way again to
show the title of the PDF document.

Mac G3 (old beige).  OS 9.2.2 (Intern. Engl.)  Classic theme.

Mozilla Build: 2002072703 (trunk).

I confirm that the various PDF problems still exist in this new build.  But in
addition, there is another aspect of the problems.  In general, if one receives
an e-mail that contains a link to a web-site and clicks on it, the site opens in
a new window.  But if it is a direct link to a PDF document, the latter (after
applying the scrolling-down-and-up workaround) appears as part of the original
mail window.  In the case of two earlier documents mentioned in this series of
reports and comments, namely <http://bmj.com/cgi/reprint/325/7354/3.pdf> and
the mail window appears as fragmentary remains.  But in the new document
mentioned by A. Wight, namely
a large part of the mail window remains at the top of the screen, leaving little
room for the PDF document even after the workaround has been applied.  The two
new attachments (screenshots) demonstrate this.

If, instead of clicking on the link in the original e-mail, the URL is copuied
and pasted into the Navigator location bar, this problem does not arise.

Thanks everyone for helping to reproduce this bug but I think we've got enough
info on how to repro this bug. What would really help is to narrow down WHEN
this happened. Netscape's internal sweetlou server just so happens to keep
Mozilla Mac Classic daily trunk builds back at least through June so I was able
to determine this regression seemed to first occur between 2002061108 and

Here's the bonsai query:
Many checkins :(

I've already tried with no luck backing out many of those changes including the
suspicious ones to the view module. In the debugger, I'm seeing the inital
mWindow->Invalidate(0) being called and also updateEvents seem to being sent so
I still have no idea why PDFs don't get initial drawn. 
cc:ing some more Mac heads if they've maybe seen other similar regressions.

Build 2002073103 solves some but not all PDF problems. On the first URL quoted
by A. Wight, namely


the PDF file now appears absolutely correctly.

On the most recent one he gave, namely

the PDF file is there in full, but still part of the original e-mail message
that contained the link, so that it appears only in the lower part of the
window, which means scrolling (not to make it appear, but to be able to read it).  

I then tried forwarding the e-mail containing the link to myself so that I could
download it again, but in Netscape 4.79, where it opened (as it should) in a new
Navigator window.

Finally, on
(once one enters my login name and password) the PDF bills can be viewed
perfectly well, but still cannot be saved to disk.

I had also wondered whether this partial fix of the drawing problem might have
solved my Hotmail bug (Bug 157565), but it has not.
