One tab on an Excel spreadsheet is running very slowly. When I go Find & Select, Selection Pane, I can see there are at least 50 shapes, all called "AutoShape 140" (no idea where these came from). Whenever I try to delete any of these (even individually), Excel crashes. I have tried everything else to solve the poor performance on this one tab. Any suggestions as to another way to delete these AutoShapes without Excel crashing? (which I believe is causing the slow performance in the first place)?
