CMD H, is not wording on Outlook. As far as I can tell it minimizes all other programs. Shutdown procedure. I occasionally have an issue when shutting down. During the cause of the day, I will have up to 10 different programs running. These are not closed in the windows sense. When going home at the end of the day, I go force quit & shut each down, one at a time. I check things like Photoshop have no images open & that none of the programs are processing anything. However, sometimes when opening excel or word (after a reboot) I get a dialog that tells me that its recovered an unsaved doc why is that, when I (presumably) saved anything prior to closing before shut down? Defrag?....do I need to defrag, my hard drives, if so how do I do that. Safari ..do I need to delete temporary internet files? If so, how do I do that, maybe I dont need to. Photoshop the background on my CS5, is mid grey, which is OK, but on my old PC, I had this set up as Black, that was done, however from the windows setup itself, which obviously the mac does not have. Is it possible to set that up on the mac?
