We recently installed the Jands Vista software and installed on a Mac Mini. The computer is our control surface. The DMX is connected to the computer via Ethernet to DMX conversion box by Entec (OpenDMX). We randomly lose control of the lights (they don't respond to a cue change). To regain control we have power cycled the conveter box, which kills the lights for half a second then comes back on. We have both incandescent lights as well as LED lighting. We've tried changing some power settings in the Ethernet adapter on the computer thinking is was timing out due to inactivity. This did not solve the problem. I'm going to find out the licensing info off the USB dongle this morning. Any ideas?
