You really shouldn't have to cycle through the "(v)olume" command. On my machine, the "excluded" nodes/elements are removed immediately. This should happen immediately, but if it doesn't, just refresh the window - you can do this by grabbing the frame and adjusting its size - slightly.

As to the range not working the second time in, this is a bug in the "old" graphics. All development is now concentrating on the new 3D graphics. The range command isn't quite finished here, but its getting close.
