if msg.isButtonPressed() then

    The natural navigation of the screens follows a stack order. this occurs naturally if you write a new brightscript function that includes a event loop for each screen. When you exit the event loop for the screen, you exit the function for the screen and end up in the next function up on the stack which is the event loop for the previous screen and the display stack shows that screen.

    It is not advised to allow any other type of navigation, though there are cases where it comes up. If it is something you think is worth the extra coding difficulty, you could keep track of all the references to your screen objects and explicitly close the screen and delete references in a flow that does not follow the stack order.
