Several posts about this and still no resolution. I'm having the same problem.
Only Add On is 'send to bluetooth' Won't allow me to delete unless in Admin mode. I'm the Admin? Any other ideas? Latest Serv Pack installed too.
Other posts and ideas did not work either.
In Office 2010 Excel, when opening a saved document I cannot click on anything except for the minimize, restore, and exit buttons at the top right. I can not click on these buttons within the document, only for the program container. When I click on the X the first time it closes the document, but I can still only click on those three buttons. The ribbon and all other buttons are frozen. They do not appear different than normal, but they do not work. I can get around this problem by opening Excel then opening the file, but if I open a saved file directly the ribbon and toolbars are locked. I tried saving a new file, and when I opened it I had the same problem. I can enter data and save the file using Ctrl+S. I have seen the post about removing the .xlb file, but I cannot find this file in Office 2010 installed on Windows 7. I have tried repairing the installation via Programs and Features, right-click, chance, repair, as well as a few of the suggested fixes for general Excel startup issues from Microsoft.
Here is the related thread. Not sure if they were having the exact problem I am, but the answer chosen by mods wasn't helpful for him either...
