We have a main portable controller for house lights and a wall mount for private suites. When I move portable from stage to front of house, sometimes it locks up on home screen, sometimes it comes up as the one for the private suites, and sometimes I get lucky and it comes up correctly. Has anyone else had any problems like this. I would think coming up as wrong controller would be some type of address thing. I usually have to unplug and reboot system 4 or 5 times for it to come up correct. Any input would be helpful at this point. Thank you, Rsmith - Verizon theater
