If anyone has the same problem... the only way I was able to get this to work is by skipping pictures:
Code:
For Each inls In ActiveDocument.InlineShapes
If Not inls.Type = wdInlineShapePicture Then
If inls.OLEFormat.ClassType = "Forms.CheckBox.1" Then
If inls.OLEFormat.Object.Value = True Then
inls.Select
Selection.MoveStart Unit:=wdRow, Count:=0
Selection.MoveEnd Unit:=wdRow, Count:=13
Selection.Font.Hidden = True
Else
inls.Select
Selection.SelectRow
Selection.Font.Hidden = True
End If
End If
End If
Next
