VL 1000 control parameter holdup

I've got several Vari-Lite 1000AI fixtures that will not respond to control commands while any parameter is active in a cue. I've already modified the fixture file to allow continuous gobo wheel movement (so I can have a split beam effect) and added control functions to reset the gobo wheel, color wheel etc, and they all work perfectly.
But no matter what I try I can't get the fixtures to respond to the control commands till all parameters are not in a cue.

Is there a way to release a fixture temporarily from the desk to allow the control functions to work?
Or something in the fixture parameters I can change that might work?

Also, this issue is present with the stock VL1000AI fixture library as well as my modified one.

Thanks for any ideas anyone may have. This is a pita problem.
