I am running Windows 7 and Office 2007.

When I open an Excel file from the Jump List, none of the commands on the
ribbon are clickable. It is just as though the program is frozen. I can make
changes to the worksheet but I cannot save them. I can close the program by
clicking the "x" in the upper right-hand corner but changes are not saved.

If I open Excel first, then open the worksheet, this problem does not
occur - the program works normally.

Has anyone else seen this?
