Is there a way to kill mozilla such that it "dumps core" and uses talkback to
dump out what it is doing?

I've seen mailnews hangs with 1.2, but I haven't since I have created a new

Maybe give that a shot?

I am running 1.2.1 on Win2K.  Currently, everytime I select mail from the icon
on the browser window or when I launch mail directly, it hangs with 99% cpu
utilization.  I had the problem last week then it spontaneously went away.

Reporter: Does deleting XUL.MFL fix the problem?
If so, this is a dupe of bug 169777

No comments from reporter for over a year... Recent builds on same platform
(Win2k) are unable to reproduce the issue.

Closing this bug as WorksForMe... 

Reporter, if you still are having this issue, please reopen this bug and provide
more details about how to reproduce it.
