Andrew,
ALL functions are very slow, 3dconnexion, Nav keys and mouse, and all menu actions. Menus take 2-4 seconds to drop down, and 2-4 seconds to respond to selection. Panning and rotating are also this slow. When I open using your objects everything works ok. It only slows when I open my own objects. They are the same objects that I have used without problems for earlier testing of morphs, etc. The objects still work fine in Studio, ZBrush, and Hex. I am sending you the log file as you requested.
When I reload version 2.08 everything works correctly. I have gone back and forth several times and the results are the same each time, 2.08 works and 2.09 B1 dosen't.
