Hello I'm using Capture Polar on a Mac running Snow Leopard. When I put a color filter or a gobo in the slot frame of a fixture I can't seem to change or delete it later. I've gone into the fixture tab and also the properties of the selected object. Each time I highlight the slot frames for either section I try to delete or move the filter or gobo and nothing happens. If I just try putting a different filter or gobo in its place it just adds the two together.

Yes, okay that makes sense. Thanks.
