I've been working with Microsoft to hopefully fix my visual studio on vista.  It's sort of a side project because Virtual PC 2007 really rocks.  It was time consuming installing XP and all the updates, and then visual studio, all just so I could run it in a window within Vista, but its actually been working out quite well.  Crashes to VS only affect the XP window; the VPC has had no effect on Vista at all.

That being said, apparently the issue relates to source control/sourcesafe, so chances are, if your visual studio crashes immediately upon opening a site via Frontpage extensions, then that site has sourcesafe on it.  There would seem to be a non-public hotfix for it that I'm working to get my hands on.  Other folks have the same problem with VS Team System, so hopefully Microsoft is going to make it public sooner than later.

What a buzz kill for coding on vista.  Que sera sera.
