This is what should appear in the top frame, after clicking the link in the bottom frame.
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; m18) Gecko/20010202
BuildID: 2001020204
Though it works in NN4 and IE, it seems that Javascript in Mozilla won't change
images over frames.
Reproducible: Always
Steps to Reproduce:
1. Load the above url in Netscape 4 or IE
2. Click on the link in the bottom frame and note that the image
in the top frame changes
3. Load the url in Mozilla and try step 2
4. Notice that it doesn't change the image.
Actual Results: The image in the top frame remains unchanged.
Expected Results: The image in the top frame should have changed.
This might be related to bug 67347, but that's just speculation.
http://bugzilla.mozilla.org/show_bug.cgi?id=67347
Also, I wasn't entirely sure on which Component to select. I picked "Javascript
Engine", since that seemed to make sense, but maybe it's HTMLFrames or such.

Confirming the bug on WinNT, and Linux, using 20010201xx builds.
The HTML of the given URL has a frameset with two frames, as follows:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<HTML>
<HEAD>
<TITLE>Change Image test</TITLE>
</HEAD>
<FRAMESET ROWS="90,*">
<FRAME SRC="changeimage-topframe.html" NAME="topframe">
<FRAME SRC="changeimage-bottomframe.html" NAME="bottomframe">
<NOFRAMES>
<BODY> Sorry, frames are needed to view this demo.</BODY>
</NOFRAMES>
</FRAMESET>

I think Mozilla is having a problem with the top frame itself:
http://filebox.vt.edu/users/abischof/javascript/changeimage-topframe.html
It is trying to load this gif:
http://filebox.vt.edu/users/abischof/javascript/images/loadingImageStatic.gif
However, we never see it. I see a space for a gif appear, and then disappear.
But never the image itself...
Browser, not engine. Reassigning to Layout for further triage -
Note: could it be a problem with preloading images? I found the
the following bugs on that subject: bug 32269, bug 41107

This doesn't work for me on build 2001-04-15-08 on Win2k. Compare how Mozilla
reacts to IE, for instance -- after clicking the link, the image in the top
frame should change to "progress bar" and stay there.

The image changes to a progress bar for me - it is a nice purple too. I'm using
a build from 4/16 on NT - Alex, can you please double-check and make sure you
have anew build? Thanks.

I just installed build 2001041604 on Win2k SP1. I have my proxy set to "Direct
connection to the Internet", and I made sure to delete my browser cache before
installing the new build.
Under Debug => Networking, I have HTTP Version set to 1.1, and both "Enable Keep
Alive" and "Enable HTTP Pipelining" checkmarked. I mention these settings not
because I consider them to be unusual, but just in case.
I go through these steps when loading the page:
1. Load the url, and wait for "Document: Done" in the status bar
2. Click the link for "This link should change the image in the top frame"
3. Then, wait for "Document: Done" in the status bar again.
At this point, the bottom frame should say "This is the second page", while the
top frame should have an animated "progress bar" animating. But, I don't see it.
I'd like for this to work-for-me, but it doesn't seem to be cooperating.

This works fine for me on both my NT and Win2K boxes using a fresh CVS pull,
debug and release builds, with the options you specified. I'm downloading the
binary now to test that.
Chris Petersen, can you check this please and note your results? Thanks.

I just tried the url again, this time with build 2001042908 on Win2k: it still
doesn't work for me. Marc, I figure that this build should be *at least* as
bug-fixed as the CVS pull that you mentioned.. Any ideas?

OK, I finally got back to looking at this - it is failing for me now too on my
NT machine. Accepting.

As Phil Schwartau noted: "I see a space for a gif appear, and then disappear.
But never the image itself..."
I just noticed that if you are quick and click the link *before* the image
outline disappears - then it works (I see the purple "progress bar" image
and it stays). Build 2001-06-01-20 on Windows 98 SE, using a slow modem link.

I think the problem here is that the original image does not exist:
<img name="progress" src="images/staticimage.gif" width="104" height="14"
But the file http://filebox.vt.edu/users/abischof/javascript/images/staticimage.gif
does not exist.
For some (bad) reason, image elements the source of which could not be retrieved
are being collapsed to zero width in Mozilla. So the progress meter image is
actually there, but we can't see it. Moreover, replacing the (non-existent) SRC
with another (existent) SRC works, but we can't see the result, since the size
of the image is still 0.
I will attach another testcase that demonstrates the problem.

Good call, Wolfgang. After having fixed the typo in my source, Mozilla handles
the situation properly. Marking FIXED.
Should another bug be reopened for the collapsed-to-zero-width problem?

hm. I wouldn't say this is fixed at all. The bug that caused the original
problem is still there.
But since I can find no form element that enables me to reopen, I filed a new
one: bug 86257.
