Backlogged on this, but I got the new SWC and zipped source uploaded, including the new RangeSlider component (HRangeSlider and VRangeSlider, actually). Has a bunch of other bug fixes in there as well.
Also updated the site, as it had a nasty bug in the WheelMenu that caused a run time error, as several as you reported. This was fixed a while back, just needed to update the site. And the site now shows the RangeSlider as well.
