I have a big problem and a small one, using 2019 Fundamentals on Mac Mojave 10.14. Big one: every little thing I do prompts the screen to freeze and slooowly (1--2 seconds) rebuild itself. Tried messing with Vworks and Doc preferences, but no change. [OK, I figured out this one -- switch to wireframe -- but still can't get renderworks to make my lines squiggly as needed for a project] Small one: I want to use a Renderworks style, and followed the advice in Help in various ways, but can't apply the line style I want. Any help much appreciated!
