Quesa interactive render crash

[Daniele C. <dca...@in...>]

There is a problem with windows version of quesa when used quesa 
interactive render.
You can try to run geom test. When you try to select "Quesa interactive" 
from menù render app crash.
If used quesa.dll debug there isn't problem.
I ask if is useful to maintain this type of rendering. I use a work 
around to resolve the problem.
If chosen interactive I set Quesa Opengl with shadows disabled.
