Hi Michael,
I re-installed Moi4FebBeta, over its previous installation, and all is well.

The file GetPointOsnappedOnCurve.js was present, but I think the problem was that in between the recent customUI upgrades, I had modified CommandBar.htm, which is no longer necessary for "AppData..." storage... Sometimes its better to "let the dust settle." :-)

So at work all of the stock Commands are under ProgramFiles/MoI 4.0 beta Feb-9-2018/commands

_prefix commands are in another commands directory a few directory levels below AppData..., but could be in the old commands folder. (I think)
