I haven't used my PowerPoint in forever, but when I tried to modify an old presentation today I could not use the mouse to drag objects. Then I tried clicking on the file menu and found I couldn't unless I right-clicked somewhere on the screen first.
Any time I click on a frame, my ability to mouse-click is gone until I right-click again.
I even reinstalled Office 2003 and installed all the updates again...it didn't solve the problem.
Any clue what the heck is going on here?
