Re: Internet Explorer Crash
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.
