When I open excel and try to use a worksheet I find that once I highlight a
range of cells (by click and drag) I can not then do anything else. If I try
to click elsewhere on the sheet the selection is extended to that point. If I
try to use a menu there is no response.

When I try to close excel I receive an error report:
szappname excel.exe
szappver 10.0.2614.0
szmodname hung app

I have tried Detect and Repair but this has not worked.

Is there anything else I can do, short of reinstalling office?

Thanks
