I'm a brand new photoshop user. I am using it for digital drawing with a Wacom Intous tablet. I noticed that photoshop is getting stuck. The program isn't freezing, I can move the cursor around and continue to use the same tool I am on. However, if I try to switch tools, zoom in/out, etc., photoshop won't follow through with the function. It seems to keep track of all the things I am doing, because once it unsticks, it quickly cycles through all the functions in the same sequence I input them while it was stuck. It is extremely frustrating, especially since I am getting more comfortable with the program and these lags are slowing everything down, as I am constantly checking to see if it stuck.
