[AccessD] Turn off the ribbons programmatically

Dear List:
 
Is there a way to turn off the A2007 ribbons programmatically?  In a way
that will not cause the program to barf if it's being run by A2003?
 
I have a legacy 2003 app that's run by the client on 2007.  The ribbon takes
up so much freakin' real estate that you can't see the whole form on the
display.  Especially the exit button at the bottom which is kind of
important. 
 
I got the navigation pane to turn off: DoCmd.RunCommand acCmdWindowHide, but
not the ribbon.
