I just instand Office Standard 2007 over Office Pro 2003. Now when I open an
Excel file the Excel window opens, then it takes a very long time before the
file opens. When I click on the "X" for the Excel window - not the "X" below
it for the open file - the file closes, but the Excel window doesn't close
until I click the "X" again.

This works nothing like the Excel 2003 files.

Can anyone tell me how I can get Excel to work as I think it should?

Thanks.

Keith
