each key event has a sub containing the menu and its key events sub , found just by changing menu pages i am trigering the crash, it takes 25 key presses of showing each page back n forth to trigger the reset

even though the menu is not got 27 levels deep it does gosub to the next page to display and then run the keys sub for that next page

ill try another way for testing , but its structure change of the entire menu system as it stands
