Problem with subForm On Current event

[kirkm]

OK I don't want STATIC. This code is in the SubForm. For a test I added the Tag :

Option Explicit
Option Compare Database
Dim bolInitialized As Boolean

Public Sub thisSub()  'This is called only by the Main Form Load event
    'set it to true so Current event can be called
    bolInitialized = True
    Me.Tag = "true"
    Call Form_Current
End Sub

Private Sub Form_Close()
    Me.Tag = "false"
End Sub

Private Sub Form_Current()

    If bolInitialized Or Me.Tag = "true" Then

This now works because when bolInitialize has wrongly changed to False, the tag corrects it. It's not I hack I want to keep (or be necessary).
This is part of the problem, as there's no problem if it's not called

Private Sub Title_DblClick(Cancel As Integer)
'Stop confirmed bolInitialized is true
    Cancel = True
    PlayFile "a"
'Stop confirmed bolInitialized is still true
End Sub

The boolean is true returning from Playfiles, but is FALSE the next time Form_Current runs.
But if no Title_DblClick it stay TRUE and Form_Current runs every time.
What mechanism might be changing it ?
