Chris, does this happen for you?

Sairuh, anyway can you confirm this?  (Like you really have a Solaris box in
your cube ... :-)

Adding "rtm" keyword because if this is confirmed, then we definitely want to
fix this.

well, i cannot repro this. then again, i'm using a commercial branch build
(non-trunk), on linux.

mcafee has a solaris box, though. :)

worksforme on solaris from a build around 10/9/2000, not sure if I need a 
newer build to confirm though.

bits?

Comment 6

[Sander van Rijnswou]

Yup, yesterdays build does it. Alt-backspace and crash. In fact when i made a
typo in 'yesterdays', I just crashed it again ;-)

Comment 7

[Chris McAfee]

reopening per user comments

Comment 8

[sairuh (rarely reading bugmail)]

confirming per above comments... 

however, i couldn't repro this using either commercial or mozilla *trunk* bits
[2000.10.11.08, nightlies] on linux. mebbe this is solaris-specific, then?

also, i haven't changed my keybindings --still using the default Ctrl for accel
key and Alt for menu access key.

[don]

Is this really Solaris-specific?

I had to bang on alt-backspace for a while to make this 
crash, but here's the stack trace I got:

There is something different in todays build. Alt-backspace doesn't crash
anymore (good!). Unfortunately control-backspace still gives an immediate crash.
(as does  control-{insert,del, home,end, pgup, pgdn, tab, F1,...})
