I have a file saved correct. For example the file name is water.xls.

When I open the file water.xls it opens and I can edit it. However, the file
name has changed to water1 (without .xls). I can reopen water.xls, while
water1 is open and the new name is water2 (without .xls). This can go on and
on.

The file in not protected and I get no error messages. This only happens in
excel.

Any thoughts of how to get the file name back to water.xls when it is opened?
