When I use Photoshop 11 either for editing or organizing, causes my Windows 7 PC to run hard and nearly crash. Deleted preference files per other instructions but didn't do anything. Has done this for last few weeks, every time I try to use Adobe. Seems to have started since last Adobe update, but there isn't a new one. Have had Photoshop 11 for nearly a year without incidents before this. Nothing else causes this/updated RAM several months ago. Any thoughts?
