I am running FormZ 8.5.7 on Mac OS Sierra 10.12.6.
I found this page in the user guide that describes the feature I seem to lack:
I have turned on controls (see attached image) but right-clicking on points, segments or faces, doesn't open the contextual menu (I want to delete an edge).
The strange this is I know I used to see this menu but I haven't used it in a while and don't know when it stopped working.
Is there something I might be doing wrong that is causing the menu not to appear?
