I've been using MS Visual Studio 2005 for a few months now and I must say it's way better than the 2003 version.  I still very much miss using IntelliJ, but what can you do?  I ran into this error message this morning.  I was trying to expand the list of contents of a project in the solution explorer.  Seemes like a trivial task.  I appreciate that they tell me something is stuck, but if they know something is stuck, why don't they un-stick it?
