I'm constantly having issues since 10.7.1. Apps are failing to launch and bouncing for an age and then when they stop they are not responding and require a Force Quit. Also, finder is constantly crashing and not then relaunching. If I try to log out it just freezes. Anyone else experiencing a deterioration in performance since the 10.7.1 release? Is there a way to roll back to 10.7.0?
