I installed ArcGIS 10.1 SP1 over a week ago. Since then, ArcMap has been crashing frequently (every hour or two). First it starts to slow down (response time to mouse clicks, redraw, selection, etc gets slower), then the screen refresh starts to fail (menus, context menus, toolbars, and dialog boxes do not display fully, and the map display doesn't finish refreshing), and then ArcMap crashes.
I also installed ArcGIS 10.1 SP1 on a colleague's computer a week ago, and he is experiencing exactly the same problems.
We are working on several different projects with different data sets, so I do not think the problem is data related. We were previously using ArcGIS 10.0 SP5 with no problems.
We both have 64-bit capable machines, but only have 32-bit OS installed (awaiting upgrade from our IT dept).
I've got a case open with Esri tech support, but no solution yet.
Has anyone else experienced similar problems? Any idea how to fix them?
I had hoped that waiting for SP1 before upgrading to 10.1 would help us to avoid this type of problem!
