Hello, I am using Rhino 6 and have encountered a problem for a couple of days now. When I try to undo, rhino either undo once or not at all, saying “nothing to undo”. I have a large memory (32GB) and I have allocated 16 GB for undo operations, still no difference. Any idea on how to fix this issue, it is really annoying and stops my workflow… You can find my system info as follows.
