Thank you everyone for your ideas! Abulafia, the Modal property basically achieved my goal.
Even without the button to fully Minimize the form, if you hit Restore on a previously Maximized form, it becomes somewhat smaller than the total Access window, and you can then click to other now-also-smaller forms that may have been behind the current form. I wanted to prevent people from clicking back to an earlier-opened form while leaving the later-opened form open.
With Modal turned on for all forms, you can still hit Restore and see all the forms as smaller windows inside the Access window. BUT, you can't actually move the focus off the current form unless you hit close. It's a little sloppier than I'd like, but it very much achieves the goal.
I found some code in the Access 2000 Developer's Handbook that was supposed to save the name of the opening form in the tag of the opened form so that it could hide the opening form until the opened form was closed. I couldn't get this code to work.
I'd also like to add that *****'s code worked amazingly well -- it results in the current form window acting as the entire application window, so if you hit Restore or Minimize, it performs those functions for the entire Access application, and you can't ever get to a previous form without closing the current form. Thank you, ******, I will probably stash this away in my bag of tricks for a future use!!! In this case, however, I'm going to use the Modal solution, because the users of this application do need the menus and toolbars sometimes.
Thanks again, everyone, this is totally resolved now!!
