When you tap on a button on your screen, it changes color to let you know it is active.
That's cool
the problem is that most of the time, it stays active, even when another button from the same group has been activated.
Ends up having the whole screen colored, not knowing what is going on...
I methodically and systematically toggle active buttons that I know should not be on at that moment... untill I press the wrong one and everyone on stage find themselves in the dark... ooops, wrong one... yeah, only funny afterwards

Please, could you fix this ? Its been a real pain for years. Only flow in a really cool app otherwise.
Thanks !
