    This is driving my a little crazy.

    First, specs:
    Macbook Pro 17", 5,2 (late 2009) 2.8ghz
    Video: 9400M, 9600M GT 512 ram
    4gigs ram
    500gig 7200rpm drive
    Snow Leopard is fully updated.

    Photoshop CS4 is just pegging one of the core's on the CPU, even when doing nothing. And, any changes I make like moving a layer, editing some typing, transforming something, it doesn't show up until I do something like zoom in or out, or change the screen mode.

    It's sort of not usable, since I can't see any changes I make without doing something to change the screen. This seems to all be started today, I don't recall these problems before.

    I ran a permission repair and a verify disk.

    Just learned - when I switch to another user, everything looks fine.

    So what would be about my user that does this? It's same plugins, fonts, all that. So what can I do to try and reset my user prefs or photoshop prefs? I have used AppZapper to delete the photoshop prefs, but that hasn't helped.

    What is that thing you can do to reset a app by holding down some keys and clicking it's dock icon? And, is there a way to reset my user prefs?
