I have a development laptop which has windows 8, visual studio 2012 (premium), and a full blown copy of Team Foundation Server.  On the same box is a developer edition of SQL 2012.  The system has 16 GB of ram so memory is not an issue.

Since UPDATE 1 I am getting freezes during "performing check-out" operations.  A reboot seems to fixes things for a while however the problem reoccurs.

 

It seems to be a timeout error.

 

Is anyone else seeing this?
