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: 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?
