App not responding

[Anonymous]

The Sketchbook app won't let me draw on the plain canvas. When I try to quit the application (I have a MacBook Pro), it doesn't respond. I therefore cannot log out of either the app or my computer. It is extremely infuriating as I can't delete the app either. Can somebody help this situation?
