When I first began usign Visual Studio 2008 it was excrutiatingly slow at saving changes, switching between tabbed files, and switching focus from another program to Visual Studio 2008. To make matters worse, any one of these tasks and a few others would cause Visual Studio 2008 to crash. After too much frustration, I decided to take a look at the options (on the menu: Tools | Options). Under Environment/General, I noticed a new setting: Animate environment tools. After unchecking it, Visual Studio 2008 has been as quick and steady as the prior versions of Visual Studio. HTH.
