CSTMENU: multilevel custom menu with soft keys

[spiff72]

This is a really cool approach to making use of the soft keys!

One question: I have used this successfully on my Prime G2 (hardware revision D), but I recently got a Prime G1 (hardware revision C) and tried it on that model, and I get really bad screen flicker on the menu "title" and on the bottom. Is this just a hardware limitation of the G1?

I need to try the "non title" version of the program yet from the OP, as I started out with the title version first...not sure if that makes a difference or not.

Thanks!
