Onquit for ctrl+w?

hi all,
i’m trying to open and close an external exe from vvvv. I open it when the patch starts (onopen attached to a shellexecute). And i want to close it when the patch stops (onquit). The problem is that, if i close vvvv with alt+f4 all is ok (i use the “finally” node). but if i close vvvv by ctrl+w shortcut (i use alwasy this instead of alt+f4) nothing to do. The window close before the finally should permit, and the .exe is still open. I searched something like “onclose” but doesn’t exist.
any help will be appreciated ;D mevvvvy xmas

onquit is your friend ! merry xmas

may OnQuit (VVVV) be with you
