I am running Windows 7 Pro 64 Bit with Office 2010. All of a sudden. i am unable to select multiple cells in Excel by using the combination of CNTRL key plus right clicking. When I do this, I get a miniature image of the open window instead of selecting the cell desired. This occurs in other programs as well so I assume it is a Windows setting. It worked properly yesterday, and I have not re-booted since then. I am in the middle of a huge project with a 104 MB Excel spreadsheet and I need to be able to move multiple cells of data urgently. Please, any ideas???
