If you want to master app compat debugging, then I really only know of one approach: practice. Find things that are broken, and then find out why. If you have to look too far for something broken, then you must be significantly luckier than I am! Now, I prefer to listen to Mötley Crüe when…

Probably the most frequent conversation we end up having these days is with customers who are preparing a migration from Internet Explorer 6 to Internet Explorer 8 (typically as a side-effect of migrating to Windows 7).

Hotfix Release of the Application Compatibility Toolkit 5.6

With relatively little fanfare (in other words, with no fanfare that I am aware of) we released an update to the Application Compatibility Toolkit 5.6.
