Thanks for confirming my suspicion. I would be willing to guess that readScript was in Poser 3 - the same guy was the default opener. Which would mean that it does pre-date ERC. ERC happens outside of much a buffer - the controlling figure is wild wild west sort of assignment - so readScript must really be dancing on the top of the berm. It would not surprise me if some more gottachas show up as hard as this is going to be pushed. The sophistication of these functions - inside this rickety structure - has already taken things beyond the fire and forget level. Maintance is required, and there is much resistance to that.
