Miscellaneous
Added a preference to workaround an issue in which selection could be very slow on some Win 10 systems. To set this preference open Command Prompt and enter:
C:"Program Files""SketchUp""SketchUp 2018"\jsonpatcheditorPreferences WorkaroundDrawXorRectUseGLFlushNotFlushDraw b true
Note: If you installed SketchUp in a non-default location you will have to update the location above.
