I have a version of DVC1 which says "Aug 9 2006" on the splash screen.
I have 4 moving heads connected each with 15 channels, sitting on channels 1 to 60.
I can go into the Group configuration window and select all sorts of groups for the fixtures, but fixture 1 seems to keep getting ignored by the grouping.
For example: In the group configuration, I put a tick under "F1" for all for fixtures. I close the group configuration window, hold F1, change a slider and fixtures 2,3 & 4 reflect that change, but fixture 1 just sits there, unaffected.
