I've 2 windows 7 machines - a desktop and a laptop. On the desktop I have SSMS 2012 and the laptop as 2008 R2. I've found that the 2012 version is slower to open (though that may be more the computer than the application) and occasionally it will lose the list of server names that I've connected to. I would love to figure out the trigger for that one because it's annoying as anything.
SQL 2008 also loses the list of server names and all my non-default options that I set up. I have found that it usually happens after an update to SQL Server or when my machine crashes or when SSMS crashes. Rarely it happens after a specific windows update.
