I purchased a bamboo tablet a few years ago and it came with Photoshop Elements 4.0 which I installed onto my mini mac and it has worked perfectly fine. Recently I purchased an Imac and installed the Photoshop on it and it worked fine in the beginning but now it keeps unexpectantly quitting for no reason. I'll open it up and start resizing a photo and it just quits for no reason. I have deleted it and reinstalled it, and tried updating it but it still just keeps quitting. Does anyone one know how to fix this problem?
