Three Scenes (and they can cycle)

After completing some of the modifications earlier today I was able to set up a generic starter file that is comprised of three scenes total: Log In, Scene One, and Scene Two.

The navigation buttons allow the student to jump back-and-forth amongst all three scenes. Every time a scene is changed the previous scene is deleted (null) and the next seen is created anew, complete with new buttons, frame, and blackboard background.

Here is a picture of scene two:

I was able to jump back-and-forth over 20 times with no apparent ill effects in the running program. (So, it looks like all of the elements are being deleted and re-created as needed without any old code hanging out and clogging up the system.)

Time: 1 hour
