Mouse

My mouse has stopped functioning inside of my Word Documents. It functions
everywhere else...ie I can click from tab to tab I can work with Excel, etc.
I can not highlight, point click or bring up the menu function (from right
click) This just began a few days ago. I have uninstalled and reinstalled the
entire suite, and I still have issues. I have chosen to update and not
update (after each re-installment) Nothing seems to change the problem.
