The problem seems to only happen on your setup since no other user has reported the same thing and we are not able to reproduce it. But when we knew that the "DMX BarGraph" did not open, we knew what part of the software did not respond so we inserted a security who relaunches this part of the software in case of no response. At this time, we does not know what caused the problem : it can be an OS issue, a conflict between hardware devices messages, and so on ...
But we will try to reproduce as much as possible.
