Systray Toolbar Bug

'*** This is a very simplistic Example
'*** Create a form with a toolbar named Toolbar1 and place the following code in it
'-------------
' FORM CODE
'-------------
Private Sub Form_Resize()
 If Me.WindowState = vbMinimized Then
  Toolbar1.Enabled = False
  TrayAdd Me
 End If
End Sub
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
 Dim Result As Long
 Select Case TrayEvent(Me, X)
  Case 1:
   TrayRestore Me
   Toolbar1.Enabled = True
  Case 2:
 End Select
End Sub
'**** this is generic code not written, only modified by myself
'*** Create a module and place the following code in it
