This morning, when starting up Excel, I receive an error message.

The message occurs prior to the opening of the default workbook (Book1).

The message reads "This workbook is currently referenced by another workbook
and cannot be closed".

If I click on "OK", the opening proceeds normally with the default workbook
opening.

In MSKB, the only discussion I could locate with regard to this message had to
do with programmatically controlled operations; but I have not introduced any
macros that should be doing this.

How can I troubleshoot this?

Windows XP SP2; Excel 2002 SP3

Thanks for any help.
