So, I have a problem and I think this might be the best place to get an answer. Photoshop has not been treating me well lately.

First time it happened was at school, so I know it's not m computer or my copy of photoshop, so I have to assume that I'm doing something wrong and/or horribly stupid. What happens is that when I open the program and try to start working on something, all I get is the hand tool. No matter what tool I have selected, what shows up on the file I'm working on is the hand tool. Then again, I just went back to my photoshop window, and suddenly it's all working again. This has happened before as well.

Has anyone else ever had this problem?
