I'm losing my mind with this OS... I'm running a 2007 silver Imac and just upgraded to SL. aside from all my apple aps (ie. logic pro studio 8) running slower than molasses rolling up a hill... my mighty mouse (wired) jumping to the corner of the screen all the time and wifi won't stay connected to my router for more than a few hours at a time (when this happens it also likes to ask me for the password it already knows... and rejects it when i reenter it??? AND NOW my computer won't shut down or restart??? i read in another thread about this happening with multiple accounts and a log out being needed... but i don't have other accounts... so i have nothing to log out from??? I'm super disappointed and am tempted to switch to windows 7, but i've already invested a small fortune into my apple and apple exclusive software like the looser that i am... anyway... if anybody can help me with any of these problems i'd love them forever... and you'll be saving a perfectly good computer from being thrown out the window.
