While researching the cause of a "can't empty clipboard" using Excel 2007, I discovered it was caused by the Skype add-in. The recommendation is to delete this add-in. Any other ideas?
Despite (trying to) delete the add-in, my excel is still corrupted. The logo is no longer the correct excel logo and although you can open the program itself directly, if you just double click on a spreadsheet, it will not cause the excel program to open and then open the file. In other words the links between IE and Excel have been broken by the Excel add-in. how do I restore them?
After I removed the Skype click to call function, my copy paste functionalities for excell 2007 were back. Before that, I was only able to paste text or unicode. It took me ages to find the solution... I also disabled automatic program updates to avoid such mishaps in the future.
