Thanks Daniel.
At some point in this thread you and Edgar asked for my game loop code so you could see the various events. Keep in mind, I didn't write it with the intent of sharing with others. If there are process improvements that I can make, I'm excited to hear them. I'm always open to learn from the more experienced. If your just critiquing my coding technique, I already know it's sloppy 
.
This code is in its own file and function. In main() I show title screen and wait for choice of Play, Setup, & Quit. If Play is chosen, we end up here.
1while (!bQuit)
