Hi @ddeschen, @itailu, @bigjimslade, @maxz, @Martin_Lines-
We have what we hope are some fixes for these issues in the latest RhinoWIP (5E12w). We would like your help testing the latest RhinoWIP to see if it resolves the issues you are seeing before we publish an 5.3.1 update.
Please let us know if 5E12w resolves these issues on your machine.
Thanks,
-Dan
