Anybody else having this problem? (Excel 2007, Windows 7). When I open a pre-existing Excel file by clicking on the file, two windows open: the spreadsheet AND a second Microsoft Excel window (no spreadsheet open--just a blank Excel Window).

When I open the Excel program directly, I get the single window (Book1). But opening Excel from a previously created file always gets me two windows.

Word 2007 does this too, but not consistently.

Any suggestions?
