			Won't pretend to know for sure what's causing this, and it would be difficult to diagnose remotely anyway.  But ... 
 
-How many apps did you have open?  Too many will cause weird effects. 
-Some pages with Java can be hogs -- try switching it off in options/preferences. 
 
Other than that, I'm guessing it's external to the machine you were using.  If it's no better tomorrow, it may be worth reporting it to your support guys, but I wouldn't expect much in the way of symapthy or immediate action. :-) 
 
Anyone have any other ideas?			 |
