Just spent a few hours trying to debug a site in windows. The site in question is this - a simple site using a few of the KISS-libs. On firefox there were no problems. Even the javascript console was quiet. BUT looking at the page with IE (the one that comes with XPSP2) the pages were totally blank.

After I found out it was about the JS in the page, I tried getting Javascript debugging to work in IE according to some instructions found from a msdn-blog.. didn't work.. finally through painful trial and error I found that the problem was that...

IE can't handle script elements that don't have a separate closing tag :-P . So you can't use <script src="blaa.js" />. Instead you have to use <script src="blaa.js"> </script>.. and this is the browser with the biggest marketshare.. oh please..
