I've had another go.
i can get the PC navigator 7.1 to launch in a window.
but i cannot get 7.1 to launch in a window in RR. where do i put the command tags?
when i get it to launch (full screen in RR) when i go back to the main menu then back to GPS it has disapeared. i do not think it has just lost focus, it has actuially closed it down (if i minimize it is not there)
