I have just opened an Excel 2003 workbook open.

However the filename looks suspicious. Instead of "Test", it is "Test:2",
i.e. a secondary version of the same file.

No-one else has it open, as it is on my own hard disk.

When I close the file (but not Excel), then go WINDOW UNHIDE, I can see
"Test:1" and "Test:2".

This is creating share conflicts, and is causing all sorts of mayhem.

It is a systemic problem, and not isolated to just this file.

Does anyone know of some bug causing this generic problem please?
