Hi all - I'm using Excel 2003/Windows XP.

It all seems to be working fine, but I notice that when I close the
workbook and reopen it, both its name and the name of the attendant
add-in which it references, appear *twice* in the Project Explorer.

Then if I close the file without exiting Excel, on the next reopening,
both the file and the add-in appear in the Explorer *three times*; but
if I close and exit Excel altogether, they both only appear once on
re-opening.

If I repeat the procedure of closing the file without exiting, it goes
on adding one in the Projcet Explorer.

Please can any one throw any light on this amazing behaviour. TIA
Charles
