I keep getting these errors when I try to crop large photos in Photoshop. This just happened tonight, I mean as far as recent history. I'm running an 800MHz eMac (upgrading to a new iMac in a few months, but this has to work for now), and I've had this problem in the past and solved it by backing up all my files and getting the HD scrubbed. Is there any other way to fix this? Everytime it has happened before, it's when I am doing something that requires a lot of system resources, such as cropping these 8MP photos. It tells me I should delete some files, but I've got more than ten gigs free on my HD... PLEASE HELP!
