How to open a patcher and close the parent.

Hi everybody,
I'm trying to make a presentation with multiple patcher and I would like the first patcher to open the second and close the first; the second to open the third and close the second and so on. I've tried with "; max first openfile first.maxpat" and the corresponding closefile but I'm not sure it's the best way, and often after a certain time, Max quit. Is there another mean?
Thanks
Fred
