I often get caught by this:
I have selection in a maximized top view in wireframe.
Reset the maximization -> perspective becomes visible -> Rhino starts to create render meshes.
There is prompt at the commandline “Creating meshes… Press Esc to cancel”
Yet if I press ESC it not only cancels the mesh creation but also my selection.
Could it be setup that the ESC only applies to the mesh creation and not also unselects my selection please.
