[AccessD] custom toolbar

Dear List:
 
I made a custom toolbar with one button - a close button - for all the
reports in preview mode in a 2003 app.  Works fine in 2003, But the toolbar
doesn't show when running the app in 2007 or 2010. 
 
But the target user for this app might be running 2003,7, or 10.  So the
problem is to find a really user stupid/foolproof way to close the reports
that are previewed.  On the client's machine - running 2007 - the there's
not even control box with an x to close the report although it shows in
2003.  
 
This is an mdb BTW but when deployed it'll be an mde.
 
Is there some foolproof, intuitive way to be sure you can close a report
being previewed?
