Compatibility with Big Sur update of mac OS

We are aware of one compatibility problem between FrameForge 4 and macOS 11 "Big Sur":  User rendering styles are not rendered in real time in the live view.  (They do, however, continue to work in snapped shots, printouts, etc.)  We believe this is Apple's bug, and have reported it to Apple.  In the mean time, we have reverted to the old behavior, in which the menu item Cameras > Force Redraw of Main View (shortcut control-R) temporarily renders with the user render style until the next time you move something or change the selection.
