Jim...
it appears only to be doing this on this one drawing... it is a complicated light plot and I suspect the issue is with the symbols and grouping them... I have had issues where the scrollers move at a different rate than the fixtures .. so maybe I'm asking the wrong questions .. or looking at the wrong problem .. it's also imported from VW14... for what that's worth ..
attached is the file ...
