Hi I installed photoshop cs5 onto my new imac, running snow leopard. I've now noticed that when I set the mac into sleep mode, it doesn't stay in sleep mode throughout the night. By morning, i've noticed the hard-drives are spinning fast and it's fully operational (out of sleep). Additionally, there is what I believe is the Adobe icon (the adobe "A") in the top right of my 'taskbar' (where the time is displayed). When I hover my mouse over this icon, it just shows a sort of revolving white-ish circle (not the usual spinning-rainbow mac one). I cant click it, I can't right click it, it just hung. Adobe programs are not, as far as I know, running in background. Is it this icon indicating that it's updating?? It stays stuck like that overnight and I'm not sure what I can do apart from shutting the mac down proper!! I can't make my mac go to sleep for more than a few hrs! Please someone help! Many thanks!!
