In PP2012 I saved a Poser box prop, and whilst inspecting the resulting pp2 file, I noticed a new switch "enabled 1" been added to every channel. I tried saving a figure, and again an "enabled 1" switch had been added to every channel. I have never noticed this switch before and have no idea what it does. I tried changing the value to "enabled 0" in some translate and rotate channels, but can't see any obvious change to how the channels work.

Does anyone have any info on what this switch does?
