Looking better solution to handle write conflicts Overlapping Windows app

Question

There are almost 100 forms/subforms in this application. This app does quite a lot. To avoid write conflicts I've pretty much created a controller that I use to open most forms in the application. It doesn't control much, it really just closes all other forms in the user's application before opening the new Form. The exceptions are some dialog forms.

I've restricted opening multiple windows because write conflicts by a single user. I've learned that users can't deal with saving a record on 1 window before going to another, AND they will leave a billion forms open if you let them. This is fine, except when they get write conflicts, its like trying to teach Chinese to a rock explaining how they can work around it by just saving their work and closing windows. =). I would like to give the users the ability to use Overlapping Windows so they can have the option to compare info in multiple forms quickly. Currently I have the system locked to only Tabbed Documents without showing Tabs. 1 Form open at any given time.

I'm thinking of using the Active/Deactive events of a form to just set Me.Dirty = False forcing the record to save when the user goes on to another window. Would this solve my dilemma? Can anyone offer me some guidance?

Thanks again!
