Correct the order of shapes on Notes Pages. Fix disappearing notes in presenter view.
Problem
Your slide notes text doesn't appear in presenter view.
Presenter view locates the second shape on your notes pages and assumes it's the notes text placeholder.
Usually this is true but not always. If the notes text isn't the second shape on the notes page, presenter view won't display your notes text.
If the second shape on the notes page happens to have text, presenter view will display that instead of the notes text.
Solution
Run this macro on your presentation. It will move the notes page slide image and notes text placeholders into the proper order.
Sub FixNotesPageShapeOrder()
Dim oSl As Slide
Dim oSh As Shape
For Each oSl In ActivePresentation.Slides
' Send body text to back first
Set oSh = NotesBodyPlaceholder(oSl)
If Not oSh Is Nothing Then
oSh.ZOrder (msoSendToBack)
End If
' Then slide image so
Set oSh = NotesSlidePlaceholder(oSl)
If Not oSh Is Nothing Then
oSh.ZOrder (msoSendToBack)
End If
' and now the order is Slide Image, Body Text, Otherstuff
Next
End Sub
Function NotesBodyPlaceholder(oSl As Slide) As Shape
Dim oSh As Shape
For Each oSh In oSl.NotesPage.Shapes
If oSh.Type = msoPlaceholder Then
If oSh.PlaceholderFormat.Type = ppPlaceholderBody Then
' Found it!
Set NotesBodyPlaceholder = oSh
End If
End If
Next
End Function
Function NotesSlidePlaceholder(oSl As Slide) As Shape
Dim oSh As Shape
For Each oSh In oSl.NotesPage.Shapes
If oSh.Type = msoPlaceholder Then
If oSh.PlaceholderFormat.Type = ppPlaceholderTitle Then
' Found it!
Set NotesSlidePlaceholder = oSh
End If
End If
Next
End Function
