The Lighting Controller

When a group is selected with red boxes around the fixtures chosen, change in value of any of the dmx faders only effects the one fixture as opposed to the same fader moving for all the fixtures. Anyone else have this issue?

Yes, I just noticed the same.

I highlighted the group, moved a fader, and only that fixture's fader moved without effecting any of the other fixtures' faders in the same group.

You are not alone.

We must check the Grouped Actions box on the bottom right in the Groups Tab in the Editor for a fader of one fixture to effect the rest in the group.

Just noticed that.
