I've been trying to find an answer to this problem for weeks, now, and I've only come across answers for brush lag. I have Adobe Photoshop CS2 running on my Macbook Pro. It used to work PERFECTLY, no lag, no bugs, nothing. Then all of a sudden, about a month or so ago, it started lagging awfully. When I crop, resize, paste, color, paint, type, select a layer, switch a color, ANYTHING, it completely freezes for about ten seconds, then resumes. It's driving me up the wall because I use Photoshop on a daily basis. I'm a student studying graphic design, so it's a BIT important that I have a nice, fast machine to run this program on. All of my others programs work fine and none of them are slow. Here are as many spec's as I can figure to give you. Sorry, I'm not totally savvy with Mac hardware. 1st Gen. Macbook Pro, running Leopard 10.5.4. 120 GB HD Processor: Intel Core 2 Duo Processor Speed: 2.4 GHzm 667 MHz Memory: 2 GB Graphics Card: GeForce 8600M GT I'm also using a Wacom tablet, but like I said, the lag isn't just with brushing or painting. I've got Bootcamp as well with Windows XP, but Photoshop started acting up well after I did all that. I'm wondering if maybe there's just a cache or something I need to clear out, but I'm completely dumb with Macs and don't really know where I would need to go to do that. I've tried to clear a few things out of Photoshop, like actions, loaded brushes, etc. I've even tried uninstalling a few "heavy" programs, thinking maybe it was a memory issue, but the problem persists. I've also tried messing with the memory usage, scratch disks, image cache, all that, and it's not changed a thing. Any help at all would be appreciated.
