Re: system freezes while using Mozilla

[Ray Olszewski <ray@comarre.com>]

This won't be of direct help to you, Karthik, but I've been seeing this 
same problem running Firefox 1.5.0.6 (the current version for all 
platforms, according to Firefox ... I assume you meant to write 1.5.0.1 
so are a bit back) on my Windows 2000 workstation.

In my case, the additional details are that the mouse continues to work 
for a bit, at least for moving the pointer, though I can't get  anything 
to respond to clicks. After a few clicks, the machine becomes totally 
unresponsive at the UI (though I haven't checked response over the LAN) 
and requires a power-cycle reset) ... I've surmised that the event queue 
gets filled up because Firefox is not responding to mouse events.

I only mention it because of the possibility that we're both seeing a 
Firefox problem, once that is platform independent but associated with 
relatively recent versions of Firefox.
