[AccessD] A2K7 Navigation Pane

Dear List:
 
A client writes to ask if the Navigation Pane (which in his screen shot is
on the left side of the screen) can be made to disappear through code.  I
don't have A2007 so I don't know.   I guess this 'Navigation Pane' is
something new in A2007?
 
Is there a line of code that will turn the pane off?  An if the user is
running 2003 is suppose it would generate an error but I could precede the
code to turn off the pane with On Error Resume Next?
 
MTIA,
 
Rocky
