Not sure what section/thread this would go into, but I wasn't sure if it went to Creativity or not.
If I click a button with my tablet, and then try to click a button with my mouse, nothing happens. It'll only let me use the tablet after I click something with it once. I can only fix this by turning it off and then back on. Why is this? Did I change a setting by accident? How can I fix this? It used to work.
EDIT: And I mean drawing tablet.
