XSToon/XSFur - Advanced Settings > Override Render Settings does not work at all

[WACOMalt]

The "Override Render Settings" option doesnt seem to work. Once enabled you expect to be able to change the 3 settings below it, but upon changing any of the 3 settings, SrcBlend, DstBlend, or ZWrite, the value will immediately return to the default, and the Override Render Settings checkbox will seem to sort of return to unchecked, though still displaying checked. Re-checking it still does not allow the values to be changed. Also the Render Queue dropdown and value seem to have the same behavior.
