Expected Results:  'Zilla should have just scrolled down the screen.

OS/2 Warp 4, fixpack #12

This also seemed to corrupt some preference files in the Mozilla subdirectory
tree. This resulted in me reporting bug #130569. I think this dump is the real
cause of that other problem.

I'll try it again after I have backed up my disks.

MAP file indicates crash is in

MyEventType::destroyMyEvent in nsTimerImpl, so this is a timer crash.

The only thing that could cause this is if event was null.

Any ideas pav?

Do you still see this on current builds?

[David W Noon]

I downloaded the 2002/04/14 nightly build yesterday (15 
April) and installed it straight away. I have not seen a 
recurrence of this bug.

To confound the issue of timing, I am now running Warpzilla 
on a much faster machine. The original bug was reported 
when run on a  450 MHz AMD K6-III with 384MiB of RAM. I am 
now running a twin-engined AMD Athlon MP 1600+ system with 
512MiB of RAM. Even though the SMP version of eComStation 
seems only to operate one CPU, it is still 4 or 5 times 
faster than the old machine, while the network interface to 
my cable modem is still running at the same speed.

I'm marking this as working for now.

If you see it again, please reopen.
