Forcing Access 2007 to run Access 2000 app WITHOUT putting everything in tabs

I have an old Access 2000 app (I don't do much Access dev these days) that a client is trying to run in Access 2007. It runs fine for the most part, except the forms do not behave as-designed when they are called/instantiated, etc开发者_Go百科: Access 2007 puts every new form inside a "Tab" of sorts, which is causing confusion on the part of the end user (modal forms they can't "tab out of," etc., seems to be the kind of thing they are mentioning).

It was designed as a typical MDI app, and ran fine that way for years. Is there a way to override Access 2007 "taking over" the forms handling?

Yes. Set Document Window Options to Overlapping Windows, then save the database (which should persist it to subsequent runs).

From here:

By default, Microsoft Office Access 2007 databases display as tabbed documents. To use windowed documents, click the Microsoft Office Button Button image, and then click Access Options. In the Access Options dialog box, click Current Database and, under Document Window Options, click Overlapping Windows.
