Why a few breakpoints don´t work in access 2010 ?

I´m seing that VBA Access doesn´t keep the set breakpoints when I save the DataBase, just like Visual Basic 6.0 (or NET) used to do.

I wonder if execution of an entire system does not continue when the autoexec macro finishes running (manually). Maybe that´s the reason why my breakpoint doesn´t work. The module where it is, is not in the range of the autoexec macro,so the flow never gets to that point. (I´m loading the source database holding the shift key, that's the only way I've seen that lets me set breakpoints and analyze the code)

I added a "Stop" command to the code, trying to simulate a breakpoint but still doesn't work. I send you a copy of the code. The previous Msgbox after the Stop runs well, so I don´t know why the stop fails.

When you load the database holding the shift key, is there a way to run the entire system ? (I mean without having to execute the autoexec macro manually)

Sub OnActionTglButton(control As IRibbonControl, pressed As Boolean)

' Callbackname in XML File "onAction"

' Callback for a Toggle Buttons click event

MsgBox "Quitar éste mensaje", vbCritical, "basRibbonCallbacks"

Stop

Select Case control.Id

Case "tgbclientes"
' In Tab: tabclientes
' In Group: grpclientes
parms(6) = min_pedido()
If parametro(125) = 1 Then
DoCmd.RunSQL ("UPDATE dbo_restricciones SET formulario='f_clientes' " & _
"WHERE programa_id=9")
Else
DoCmd.RunSQL ("UPDATE dbo_restricciones SET formulario='f_clientes_america' " & _
"WHERE programa_id=9")
End If
