I don't remember SSMS ever crashing on me. BTW, I'm using SSMS 2008 even with SQL 2005 because of a couple nice features absent in SSMS 2005.

>P.S. Something really weird happened to me for the 1st time in all the years I use SQL Server. I just had SSMS crash; never before experienced that. I simply selected to modify one of the tables and it crashed. When I started SSMS again it showed me the files that I can recover (queries). I wonder if this was the issue with SSMS or my SQL Server caused the crash?
