Odb getting changed to odt

Every so often when I Save-as my current open base *.odb file to a new name, (for example: foo-12.odb is open, and I save-as to foo-13), it gets changed to that new name, but with a *.odt extension (e.g. it becomes foo-13.odt).

Any ideas on what I’m doing to cause this?

Oh, heck I just figured out what is happening. If you do the Save-As while you’re in a Form, then the form gets saved as an ODT. This might be useful, but not as a backup of the odb.

So to make the backup of the odb, I must always be in the Tables/Queries/Forms/Reports selection window.
