Many thanks for your support. I prefer this, because I actually fixed a roblem with a more robust algorithm. In SU2024, for whatever reon, the old method suffered from precision versus SU2022.
@Dave-R Got it! Thanks Dave...it did seem like overkill to lock both the viewport and the layers, but it seemed like one of my viewports was shifting (even though camera positions weren't changed) and I thought maybe I had been double-clicking into the viewport(s) w/o realizing it. Still not sure what I did, but it seems to be working now.
