Hello - I am running on a 2008 Mac Pro, running Snow Leopard. Lately I've been putting my computer to sleep to save power. However, when it "wakes up", I can use already running programs, but I cannot launch any new ones. For example, I just tried to open "About this Mac" and it bounced a few times in the app bar, but then just stopped and the action disappeared, and the program never launched. I have Firefox and itunes open all the time (before/after sleep) so those are currently working without an issue. However, If I try to run any other program, Microsoft Word, BBedit, and so on.. They bounce a couple times then disappear. The problem goes away entirely when I re-start. But this makes my sleep mode completely useless. Any advice? Thank you!
