I've made a nav bar using buttons, and have them working just fine for Up, Over, Down, and Hit. (okay, so hit isn't a state, but I'll count it is as the fourth one)

Problem is, once clicked on and produces a change in the flash, I want the button to not return to the Up state, but to visually be different so you can tell you are in that section.

First problem is I can't for the life of me think of what that state is called.
(Makes it hard to search for, and my poor little brain is fried right now.)

Second problem is, can I force a button to not go back to up state? (either the over or down state would work fine).

Or do I have to detect the click and then make a call to swap out the button file for the relevant section?
