I have never saved a scene in P8.  I prefer to do a render first.  At the moment I am sticking to basic scenes  i.e. 2 or 3 figures and a background with 2 perhaps 3 lights.  P8 is not crashing every time I load from a library..  Perhaps 1 in 3..

Right now it is ten past yesterday..    Bedtime,   tomorrow then..
