VBA issue with running Workbook_Open upon opening

Question

When a user opens my VBA program it hides all Excel's command bar's and whatnot so it looks as if my program is not running in Excel at all. Since this action will take place across all instances of Excel I found some code that will check if other programs are open, and if so save my program as a temp file and reopen it in a new instance of Excel.

The problem though is when it opens it doesn't fire off the Workbook_Open event. As a temporary fix I've put a button on a spreadsheet that runs the macro to launch the program but I need to do better than this. Can you take a look at the code at this site and let me know why the Workbook_Open event is not firing? (as you can see I've already asked the forum twice for help on it with no response).

Updated with code

The code that duplicates the program and opens the new instance is in the UserForm section of code at the bottom.

Placed in ThisWorkbook:

Private Sub Workbook_Open()

    Set clsAPP.XLAPP_ORIG = Application

    If Application.UserControl Then
        If Application.Workbooks.Count > 1 Then
            Application.Visible = False
            DoEvents
            frmCreateReplicant.Show vbModal
        End If
    End If

    Call ThisWorkbook_CompleteOpening
End Sub

Placed in standard module:

Option Explicit

Public XLAPP_Copy           As New Excel.Application, _
       clsAPP               As New clsXLApp

Public Sub ThisWorkbook_Open()
Dim intMaxRow                   As Integer

    If Application.Workbooks.Count > 1 Then
        Application.Visible = False
        DoEvents
        frmCreateReplicant.Show vbModal
        'Call ThisWorkbook_CompleteOpening
    Else
        ThisWorkbook_CompleteOpening
    End If

    ThisWorkbook.Saved = True
    Delay

End Sub

Sub ThisWorkbook_CompleteOpening(Optional Fake)

    'MsgBox "...Any other OnOpen code here..."
End Sub

Function Delay(Optional SecondFraction As Single = 0.2)
Dim sngTimeHack As Single, dtmDate As Date
    sngTimeHack = Timer:   dtmDate = Date

    If sngTimeHack + SecondFraction < 86400 Then
        Do
            DoEvents
        Loop While Timer < (sngTimeHack + SecondFraction)
    Else
        If dtmDate = Date Then
            Do
                DoEvents
            Loop While dtmDate = Date
        End If

        sngTimeHack = (sngTimeHack + SecondFraction) - 86400
        If DateAdd("d", 1, dtmDate) = Date Then
            Do
                DoEvents
            Loop While Timer < sngTimeHack

This works to hide the Ribbon/command bars (although the File or Backstage menu is still present, thought I think you may be able to disable this I have not tried yet), if you are hiding other stuff like the StatusBar, etc., it may not be enough to solve your problem, but here it is anyways.

Using the CustomUI editor, open the XLSM file.

Note: The XLSM file should not be open in any instance of Excel when you are opening it through the Custom UI Editor. If it is open in Excel, the modifications to the XML will not be saved properly.

Once you have the file open in the CustomUI Editor, you'll see this:

From the menu, Insert Office 2010 Custom UI Part:

Then copy and paste this XML:

<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui">
    <ribbon startFromScratch="true" />
</customUI>

Finally, save & close the file through the CustomUI Editor, then re-open in Excel. You should see that the while this file/workbook is active, the ribbon does not exist.

But, if you switch to another Workbook file, the ribbon will re-appear while that file is active.

The startFromScratch property makes it so that when this Workbook has focus, the only ribbon elements which are displayed to the user, within the Application's window, are those which are defined within the XML, which as you can probably gather in the snippet above, are none.

This also entirely avoids the need to try and open copies of the file in a new instance of Excel Application, which (unless you have some other quirky requirements) seems unnecessarily cumbersome and problematic.
