How much do you have going on in the materials? Is the Mat Room full of nodes? This tends to make Poser slow down a bit. I assume this is the same image you had been working on previously with the background image? You had mentioned that it was going to have a dragon. Is that a high-poly figure with high res textures? I am assuming you also have your warrior in some decent armor. Lots of shininess going on via nodes? It does appear something may be wrong though. Unless you have lots of nodes/textures going on, I don't think it should be going for 10 hours without at least beginning the render. What are your render settings up to? Production quality? That tends to slow things up too. I have gotten into the habit of doing my own manual settings for final renders. The auto settings at the upper end tend to be overkill in some areas, and sometimes wind up skewing my work.
