Thank you Airmarshal for illustrating a point I have asked before without anyone being interested. The main window often looks better, especially with high resolution handpainted photographs as texture. The problem with taking a screen dump is that it can't be any larger than your screen size. Why not render like it looks on the screen? "What you see is what you get" is a philosophy I approve of.

As far as I am concerned, the render destroy my work.
