Gentlemen,

The honors go to you, the faults (as usual) are all mine.

I believe I've pinned it down to the way I implemented the loading of the form's menu. Basically, the menu got defined over and over again.
To no surprise, since (This.cMenuName) holds a unique variable every time.

* Form Activate, previously
  DO 'Menus\Main.mpr' WITH THIS,.F.
  RELEASE PAD ExitForm OF (THIS.cMenuname)
  ACTIVATE MENU (THIS.cMenuname) NOWAIT

* Now
=SYS(1104)  && Manual garbage collection of sorts, thank's Jos!
TRY
	RELEASE MENUS (THIS.cMenuname)
	DO 'Menus\Main.mpr' WITH THIS,.F.
	RELEASE PAD ExitForm OF (THIS.cMenuname)
	ACTIVATE MENU (THIS.cMenuname) NOWAIT
CATCH TO oException
	DO 'Menus\Main.mpr' WITH THIS,.F.
	RELEASE PAD ExitForm OF (THIS.cMenuname)
	ACTIVATE MENU (THIS.cMenuname) NOWAIT
	oException = NULL
	RELEASE oException
ENDTRY

I don't know exactly how VFP handles this sort of thing internally, but one can hardly blame it for getting overloaded and -eventually- crashing.

Best Regards

Peter
