Hello.
Our rig changed quite a lot during the fit-up and some lights which started with scrollers are now just plain units. I was at the desk just now and decided to try deleting channel 21 pt 2 as 21 doesn't have a scroller so it makes sense to have a normal tombstone. When I hit enter I heard scrollers move in the rig and what sounded like a VL1000 focus mechanism move!
I hit 'undo' and went to the rig check cue and found everything still works but why did stuff move when I did the delete? I tried again using a different unit and the same thing happened again.
Eek!
