Mozilla locking up

[Steve]

I have a friend who is running the latest mozilla ( mozilla-1.4,2 ) with
no plugins except the default libnullplugin.so on -STABLE and he is
reporting that mozilla locks up as soon as he trys to type in a URL, or
even clicks in the URL box. He has re-installed 3 times with the same
effect.  Could this be hardware related because I dont see any discussions
on the mailing list regarding this?
