If you try to minimize the messenger window, apprunner crashes Steps: 1. launch apprunner, launch messenger 2. minimize messenger window 3. crash Machine and Build: win98 build 1999070908 NOTE: This was not a problem with linux 1999070908 or mac 1999070908 Other Comments: This seems to only happenw with the messenger window...minimizing apprunner, ender, plaintext editor and manage history windows does not crash.

Not good. cc: putterman and bienvenu. Jay - do you have a Talkback incident report for this?

Here's the stack trace - it seems layout or tree control-related. perhaps it's related to the general tree control problems.

since the stack trace has already been given, here is my incident id: 10964108 if you need it.

I'm not seeing this any more. Marking fixed.

I'm still seeing this, and I think I've pulled all the interesting changes.

Sorry to do this, but I'm still seeing this and I have all of your changes. So I'm going to reopen.

Ok, interesting. I can't reproduce it on my machine. I could add a null check to stop the crash, but the values that you have to have to see this crash indicate something wacky is going on. I'm even using win98.

Have you opened a folder? It might have to do with having something in the thread pane.

*** Bug 9380 has been marked as a duplicate of this bug. ***

Fixed with recent checkin.

Yep, works for me now. cool.

setting target milestone from blank to M8.

claudius and i agree: verified with the friday, 1999-07-09-08 builds.
