I am having problems opening files in SQL Server Management Studio.
I can connect fine to the local database (SQL Server std. 2008 R2), but when I do File > Open > Open File, the dialog just hangs until it says ‘Not Responding’.
It does eventually connect, but hangs for a period of 20-30 seconds to navigate between each folder on the local network.
I do not have the same problem navigating the same folders with windows explorer or Visual Studio 2012. It seems that this only occurs with SQL Server Management Studio.
I have tried to find a thread to find a resolution, but the only thread I did find had the link removed to the solution!
If you have any network share, remove it and try.
Probably, Open file dialog is stuck at one of the mapped drive?

Hope that helps.
PS: Have you installed latest SP?
