Mouse Problems
 

Yeah, i haven't used Maya in a while since school started, but I noticed that I can't click on the toolbox anymore, I can only double click, but I can't select tools that way. also, right clicking on objects no longer brings anything up, it doesn't do anything. if anyone knows how to fix this problem, please don't hesitate. it would be much appreciated

Make sure your NumLock and CapsLock keys are turned on.
