I’m experienced with MS access but just starting programming in PowerPoint.  
I have used several controls (buttons and textboxes) from the controls
toolbar.  The controls are grouped with a shape to give the illusion of a
pop-up window.  When I click on the button the shape becomes invisible but
the controls do not.  If I go to the next slide and then return the controls
are then invisible.  If I use an Action Button instead of a Control Button I
don’t have this problem.

So……..  why won’t the controls go invisible when clicked?

Code for the control button:

btnCloseModifySetpoint is control button
txtNewDemand is control textbox

Private Sub btnCloseModifySetpoint_Click()
   Me.Shapes("grpModifySetpoints").Visible = msoFalse
   Me.btnCloseModifySetpoint.Visible = False
   Me.txtNewDemand.Visible = False    
End Sub

Thanks,
