View-->Headers--All overfill all message pane preview


(Thunderbird :: Message Reader UI, defect)

Not set


(Not tracked)



(Reporter: Aureliano, Assigned: BenB)



(Keywords: regression, Whiteboard: Fixed by patch in bug 525302)


1. enable message preview and set view-->headers-->Normal;
2. open a message in new window;
3. in standalone window, select view-->headers-->All;
4. close standalone window;
5. select another message (up or down) in message list: the new message select show all headers but headers pane overfill all message preview area.

A workaround for this issue is to goto view-->headers and magical headers pane resize.

It happens also in safe-mode. No errors in Errors Console.

Yes, I see the same. It happens in the stand-alone window only, not if you just open the message in a new tab. Thus, while View > Headers equally applies to all windows, the show_header_mode attribute is apparently only reset for the current window in which the header view is changed.

Unfortunately, this needs to block bug 489609 as a regression which will have
to be fixed. :-(

A particularly painful aspect of this bug is that restarting doesn't make the
problem go away; the workaround is that the user has to turn off "Show All
Headers" mode and turn it back on without the standalone window involvement.  

It does, however, appear to go away on Mac if a menu is opened that causes a
submenu to open over the message header pane thereby forcing a repaint.  Or
something like that.  I haven't yet been able to nail it down precisely.

If we ship without taking this fix and without backing out bug 489609, we
should probably relnote the workaround.
Bug 525302 checked in, on trunk and 3.0 branch.

Verified fixed in Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/20091110 Shredder/3.0pre, no issues when changing header views in stand-alone windows. The "more" button now allows the scroll bar to appear as well again, so that works as intended too.
