Hide/Show Menus/Tool Bars- Hides Tabs

Hello- I'm trying to get excel to hide my menu bar and all the tabs in Excel 2003. To do so, I'm using the following VBA:

On Error Resume Next
        With Application
           .DisplayFullScreen = True
           .CommandBars("Full Screen").Visible = False
           .CommandBars("MyToolbar").Enabled = True
           .CommandBars("MyToolbar").Visible = True
           .CommandBars("Worksheet Menu Bar").Enabled = False
        End With
On Error GoTo 0

The problem is that when I active this, excel grows beyond the bottom of my screen and I can't see the tabs at the bottom of the workbook.

Any advice?
Thanks!
