I can't wait to see how well this actually works:
"One of the challenges when troubleshooting web pages is finding exactly where in the style hierarchy that font size has been set. With this version of the IE Developer toolbar we can now right click on the current style being displayed and select “Trace Style” which will then bring up the window in the screenshot below with the source of the style sheet and highlighting the rule that is in this case specifying that TD elements have a font size of 11px."
If it works well that will be a great feature as there are occasions on big projects where I just can't keep track of the entire cascade. I'll take a shot with it tomorrow maybe. I've been meaning to reinstall* IE7 anyway, so that might be a good excuse.

IE7, by the way? Still only accounts for 23% of the Internet Explorer visitors to drunkenfist.com. This transition is going to take forever…
*I had to uninstall it to use a fully functioning version of IE6 to test a site that used both conditional comments and the AlphaImageLoader PNG hack. I've got a Browsercam account at work now, so I don't really have to worry so much about having the full IE6 laying around.
