Whats wrong with this code?

This is the code in my form to make the form visible again once the system tray icon is double clicked... but it doesn't even fire when I put the mouse over the systray icon.. When I added the systray icon. i set NOTIFYICONDATA valiable .hWnd property = frmMain.hWnd which I assume is how it binds the icon in the tray to the form.

Code:

---

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    'Event occurs when the mouse pointer is within the rectangular
    'boundaries of the icon in the taskbar status area.
    Dim Msg As Long
    Dim sFilter As String
    Msg = X / Screen.TwipsPerPixelX
    Select Case Msg
        Case WM_RBUTTONDOWN
        Case WM_RBUTTONUP
        Case WM_LBUTTONDBLCLK
            Me.Visible = True
            Me.WindowState = vbNormal
        Case Else
            'DO NOTHING
    End Select
End Sub

I don't know if any of this might help, but you could look it over:
