sounds like something different than what I saw.

Does your client do a "menu_set_main" command?

It looks like it may be possible that after your client stops, the main
menu item is still set so when the main menu is attempted to be brought
up, it still thinks the main menu is the menu your client set as main w/
the menu_set_main command?
