In the 01/10/2000 and 01/11/2000 Seamonkey builds. The mail window will freeze the entire application if you: 1. Select a subject in the subject pane and wait for the message to load. 2. Press the '_' button on the window's title bar to iconify/minimize the window so that it only appears on the WindowsNT application/status bar at the bottom of the screen. 3. Click on the Mail window's button in the WindowsNT application/status bar to maximize it again. When I break in the debugger to see where it is at, it keeps cycling through the following stack trace: USER32! 77e74a2c() nsWindow::OnResize(nsRect & {...}) line 3337 nsWindow::ProcessMessage(unsigned int 71, unsigned int 0, long 1236916, long * 0x0012df44) line 2894 + 24 bytes nsWindow::WindowProc(HWND__ * 0x0aff061e, unsigned int 71, unsigned int 0, long 1236916) line 689 + 27 bytes USER32!

This is in the release build as well.

I'm guessing a layout change caused this, and the only related-looking thing in yesterday's bonsai log is troy's stuff. Troy or RickG, to whom should this be assigned?

troy sez this is a box bug for evaughan

That's not what I said. I said that there wa lots of stuff like framesets and boxes on the stack.

PDT+

For the record: I don't see tables on the stack, and my change yesterday involved incremental reflow and table cells. Looking at this stack, I don't see any indication that it is related to my change

targetting M13

Ok. If you minimize the navigator window it works fine. If you minimize the mail window it crashes in the tree code with an assertion: "Reflowing row group with unconstrained height at line 995. I talked to hyatt and he says this will happens if trees are put in div tags. The solution is to remove trees from any div tag their in the mail news dialog. So I'm reassigning this to the owner of mail news.

M14, cc alecf

Seems to work ok now.

Linux (2000-01-21-08 M13) Win32 (2000-01-21-09 M13) I try it, Mail does not freeze any more. But I do not have a debugger to check though. Mark it verified. If anyone disagree, please re-open.

This is happening again in my 01/26/2000 WinNt build. The stack trace is different everytime I break in the debugger and then continue, but it is always in the resize/reflow code.

Adding evaughan to the cc list, clearing worksforme resolution.

Reassign to rickg. Seems like lots of Gecko code in this stack trace.

Putting dogfood in the keyword field.

Troy -- I hate to add burden to your list, but I could really use your expertise to kill this puppy.

I can't reproduce the problem using today's build. Maybe it's been fixed between 1/26 and today If this is really a generic layout problem, then it should be able to be reproduced using an HTML or XML example that I can run in viewer. That would make debugging of things like this much easier

1) I have only seen this problem on linux, ducarroz said he's only seen it on mac 2) it took us months to write the compose window, it would probably take just as long to distill it down to a similar example.

The bug says it happens on NT, and I'm running NT and it doesn't happen for me. That suggests either it's no longer a problem or it's platform specific. If it's platform specific, then it's most likely not a layout problem and there is probably a widget interaction

I'm not able to reproduce a freeze using today's builds on linux, mac or NT. I tried both minimize|Quit|restore and minimize|restore within session. I am, however, seeing a repaint problem with the folder pane/sidebar in the mail window after restoring from minimized state, only seeing this on NT 4.0. I'll log this separately. Will mark this bug verified worksforme. If someone sees this, they can reopen.
