When I try to use any tool on Gimp 2.0 on the canvas with my pen, the outline of the pen tool at your size does not move along with you and when I apply pressure nothing happens. On the other hand when I use my computer mouse it works properly. All the buttons, like when you choose a tool or file,edit, etc. They work fine it just seems to be having trouble with the canvas when I attempt to color. Also when I try to use my eraser it doesn't seem to reconize it but has the same problem as the pen on the canvas I explained before. I hope this makes sense so we can straighten out the problem. Thank you for your patience and time.
