When I attempt to create a chart in PowerPoint for Mac 2011 (v14.4.7), I get an error stating “To insert a chart, you must first close any open dialog boxes or cancel editing mode in Microsoft Office Excel.” From my research on the internet, opinions indicate that the error stems from a bad Microsoft Office preference file. Does anyone know if this is true, and how do I locate and delete the preference file? Can’t find any other solution to the problem. Any other suggestions? Does anyone know if updating would solve this problem?
