Prueba añadiendo al formulario lo siguiente:
A nivel de módulo:
Private Const SWP_NOSIZE = &H1
Private Const SWP_NOMOVE = &H2
Private Const SWP_NOACTIVATE = &H10
Private Const SWP_SHOWWINDOW = &H40
Private Const SWP_FLAGS = SWP_NOMOVE Or SWP_NOSIZE Or SWP_SHOWWINDOW Or SWP_NOACTIVATE
Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Y en el evento Load:
SetWindowPos Me.hwnd, -1, 0, 0, 0, 0, SWP_FLAGS
Espero que te vaya bien.
