Hi Guys, I have a client which they have 3 colour touch screens, The last time i did modification was 2 years ago. on of the slave screen does not response to pressing any cbus controlling buttons. You can see the states changes on the button for a while then it goes back again to original state in about 5 seconds. I had re uploaded the project, made it master and reset it, but no affect. You can see the state of the lights, correctly, and you can navigate to all pages, however you cannot control anything. Any suggestions
