You need to do that preference delete trick mentioned in a previous thread. That made a world of difference for me. I'll look for the link. 4.1 is the fastest & most stable version I've ever used. I'm not even going to upgrade again. lol
After I changed the preference file name, LR 4 was just as fast as LR 3. Thanks to amoline and others for posting up the "fix".
