Open Workbook - Hide Sheets/splash Screen

I have a workbook that has worksheets that serve as data input pages for the user.
I have control boxes created by the forms toolbar.

I created a splash screen that is to be launched when the file is opened.
Instead, often the last sheet that the user was on when they last saved the file (usually but not always the worksheet called "Main Menu") is seen first.

I understand that not all the sheets can be hidden - that one must be unhidden.

So I created a sheet called "Background" that is a solid color with no gridelines.

Objective:

When the file is opened, I want the "Background" sheet to be seen first and then the splash screen to be initiated.

Now - when the user opens the file, the Main Menu worksheet is seen for a few seconds (or whatever the last sheet was on before it was last saved), then it disappears and the solid background screen is shown with the splash screen. When the splash screen ends, the "Background" sheet disappears.

Here is the code that I have in the workbook


Private Sub Workbook_Open()
Dim wks As Worksheet
On Error Resume Next
For Each wks In ThisWorkbook
If wks.Name "Background" Then
wks.Visible = False
End If
Next wks
End Sub

What has to be changed so that the first sheet that is seen upon opening the file is the "Background"; then the splash screen happens; then it returns to the Main Menu sheet?
