First, check to make sure the workbook isn't actually open:

Window|Arrange|Tiled

If it's not visible, then sometimes one of these works:

Tools|Options|General|Ignore other applications (uncheck it)

--- or ---

Close Excel and
Windows Start Button|Run
excel /unregserver
then
Windows Start Button|Run
excel /regserver

The /unregserver & /regserver stuff resets the windows registry to excel's
factory defaults.

Excel opened first, when I double click on the file it will open.

Any thoughts?
