The 4 hard keys near the screen (tools ...) are programmable, according to the help screens. But when I double-click on either the far left one or the far right one, nothing happens. Also, if I relabel one of the center keys, I don't see the label appear on the simulator.

A related problem - I had two buttons on the Home screen to see which I likeed. I then deleted one of them and moved the other. Now, even if I exit the program and reload, the simulator shows the two buttons, "grayed" out. What am I missing?

Thanks
