Control panel buttons greyed out and not working

Hi again,

I'm trying to devellop a workflow with a character to go live in different settings and media. I've experimented a lot with the body control in Beta version. A great feature, but for my purpose it's (still) a bit too unresponsive and unpredictable. So now I'm experimenting with a 24" touch screen to control movements and actions with triggers and control buttons on screen.  The problem I'm struggling with now is that the trigger control buttons work fine, but suddenly they grey out after a while, and I can't get them back to work in 'perform' modus. I must be doing something wrong, I just can't figure out what it is 🙂
