When working on 3d models and switching views either to plan, elevation or isometric, the screen goes black.
Handles come up on objects when clicking but the whole viewing area is black.
The toolbars remain as they should and otherwise seem to be functioning ok - nothing freezes, the whole screen is just black.
Sometimes the view comes back when I go to wireframe view, other times when trying to do an open GL the whole image becomes pixelated or partly disappears.
I'm using vectorworks 2016 fundamentals with renderworks on an Imac, latest OS. screenshot of what my screen looks like at the moment attached
