The following problem occurred numerous times:

While working on an EXCEL file A.XLS, the program stops responding and I
have to terminate the application.

When I then try to open file A.XLS file, I get the message:

==== A.XLS is locked for editing by €˜USER. ====.

The USER is I and there are no other users.

How can I UNLOCK the file without restarting the PC?

EXCEL 2000 Ver. 9, (SP-3) running on W2K Ver 5 (SP-4).

Thank you for your help.
