Re: Internet Explorer Crash

["Thor (Hammer of God)" <thor () hammerofgod com>]

Actually, I just get a message that says "A script on this page is causing 
Internet Explorer to run slowly."  But my CPU usage for iexplore.exe is only 
at 20, and my system didn't slow down in the least.  I went ahead and told 
IE to continue to run the script, and pops up again in a bit asking me the 
same thing.  Finally bored, I say "no" and it immediately came up with 
"Goodbye" on the page.

If this actually makes Safari and Konqueror crash, why the "stop using 
Microsoft products" recommendation?  At least IE is smart enough to tell me 
that your little "stupidInternetExploder" script is being pesky.
