Reasons Internet Explorer can crash  
OK, we're currently having a problem where some people using IE 6 with XP SP2 are experiencing intermittent crashes at a single page within our site.

Looked over the code, and nothing suspicious is going on there. I added entrance and exit tracing to all of the JavaScript functions, and the crash seems to be called outside of any of our JavaScript. I tried searching for reasons Internet Explorer might crash, hoping one would give me a clue where to look. Here's a partial list I found in the first 10 minutes why various iterations of IE might spontaneously die:

  • Randomly dereferencing null pointers in the script debugger

  • PNG images with extra information in the header.

  • Display is set to less than 256 colors and a Java Applet is loaded.

  • A page with <input type crash> in the code.

  • Or <object classid=\"clsid:0CF32AA1-7571-11D0-93C4-00AA00A3DDEA\" />

  • Or Wnd = window.createPopup(); Wnd.document.body.innerHTML='<meta http-equiv="imagetoolbar" content="no">';

  • Or var crashWin = window.open('http://crash:x','','height=100, width=100'); crashWin.location.reload();

  • Or <a href=shell:windows\\system32\\calc.exe></a>

when you say SP2, is that the most recent security patch that MS is sending out?

Service Pack 2. The next "Big Thing" for Windows XP.

Right. "Service Pack 2".

Those are pretty effective crashes, too... Just threw it in some html and blammo, good by IE.
Opera shrugs and carries on...

friend of mine attempted to load it on her 'puter, and it screwed things up enough to make her have to reinstall windows.

I particuarly like
<input type crash>

I am guessing you didn't have this problem with sp1. If it is an SP2 only issue I could put you in contact with someone to fix it.

I could only get a couple of them to actually crash IE.

the object classid="blahblah" was one
and one of the js ones.

of course they all work fine in Opera :)
