Disable regen?

[FlailAway]

Hi, just found this WB and stunned at how great and simple it is for GT pulleys. Thank you.

But, I have a rather large pulley and when I am adding other stuff to the Body it keeps regenerating on entering and leaving every function within that Body. I have a fairly fast laptop i5, 1100 series,16GB-RAM and SSD but it is stalling for 6-8-seconds at a time. That gets irritating fast. :)

Is there some way to prevent visual regen? The Screw-thread WB has an option to block regen with the "Model Thread" and displays just a plain hole if un-checked. Once I am happy with the GT-pulley design, I no longer need to see the grooves.
