When I need to shut down/restart the computer, I quit out of all my programs. For some reason, the Adobe programs take forever to quit and most of the time I have to force quit out of them. If I hit Restart without quitting them first, it times out -- usually because of Illustrator. I'm on OS 10.2.8 with CS versions of everything. I can quit all my other programs while I'm waiting for one Adobe program...
