Controlling focus

This application has a “splash” page that is controlled programmatically. The db PostOpen code displays the document based on the date that the db’s [Administrator] sets in a control document’s date field. The result is that the database can have a splash page that’s opened every time for a settable period of time.But …

When the document displays, even though it’s out front, it does not have focus. So when the user presses ESC, expecting the document to close, the application closes instead, but leaves the Splash document displayed.

So …

How can I force focus to the Splash screen document, even when it’s in Read mode?
