Unspecified Error in Sql Server Management Studio

Unspecified Error in Sql Server Management Studio

I just started getting an error window with "Unspecified Error" in MS Sql Server Management Studio 2005. I get this when trying to Create a New Table in a DB or Right Click > Design on an existing table. I am able to open up a new connection and query the DB without any problems. The error message obviously is no help. Any thoughts on what is the cause and how to fix this?
