So part of the application I'm working on is still written in classic ASP. Visual Studio 2008 **was** working just fine to debug the classic ASP, and with the addition of a hotfix it wouldn't even crash when I stopped debugging. This was all working very well for a number of months.

Yesterday and today, several members of our group noticed that when we tried to debug classic ASP now, the IDE would hang immediately after trying to step into, or over a line of code.

The culprit as far as we can determine is a hotfix or update that was sent down with our corporation's SMS updater. The log files have been very unhelpful so far, and we've tried pretty much everything. This is not localized to Visual Studio 2008 either - we also tried going back to 2005 and the same symptoms appeared. Does anyone have **any** idea what's going on?? 

(Other things we've tried: Rolling back to a previous system restore point, reinstalling visual studio 2008 sp1, shutting down all add-ons, resetting environment defaults, uninstalling any update in Add/Remove programs that was installed in the last few days, using the SMS toolkit to root through the logs to find the culprit)
