[AccessD] Prevent displaying a form until...

I am starting to test my table driven Presentation Level Security system.  I have a login etc.  When 
a form opens, in the OnOpen I initialize an instance of the class that will drive the security for 
that form.  I do it there because I can set Cancel = true to force the form to shut back down if the 
user is not allowed to use the form.

The problem is that the form *displays* even if it eventually shuts back down.

This is an issue because I pop up a message box saying that the user is not allowed to open the 
form, but it is already open and displaying data behind the message box.  Oooops.

The only other time I have addressed this issue I opened a dummy form in front of the form being 
opened so that the form actually being opened was hidden.  That is an ugly solution to a common problem.

Has anyone solved this problem in an elegant fashion.
