Excel 2007: Ribbon set to hide, but doesn't before User Form opens.

My first post by the way, so here goes.
I have excel set to open into full screen and hide everything except the title bar.
I worked perfectly until I added the load userform command into the string.
I have also tried moving the command into another private sub and running a call macro to load it from another module.
No matter what I do the userform loads before the ribbon hides.

Another tips on cleaning up my code are welcome

My code looks like this:

Private Sub Workbook_Activate()
    On Error Resume Next
    With Application
        .DisplayAlerts = False
        .DisplayFullScreen = True
        .CommandBars("Worksheet Menu Bar").Enabled = False
        .CommandBars.ActiveMenuBar.Enabled = False
        .CommandBars("Full Screen").Enabled = False
        .DisplayScrollBars = False
        .DisplayFormulaBar = False
    End With
     
    With ActiveWindow
        .DisplayHorizontalScrollBar = False
        .DisplayVerticalScrollBar = False
        .DisplayWorkbookTabs = False
        .DisplayGridlines = False
        .DisplayHeadings = False
        .DisplayPageBreaks = True
    End With
    
    Load UserFormOpen: UserFormOpen.Show
    
    Application.ExecuteExcel4Macro "SHOW.TOOLBAR(""Ribbon"",False)"
    
End Sub
