Prinzeugen, From what you said, Poser has not finished Rendering. I have noticed that during rendering if you scroll the window past the point that it is currently rendering it will smear what it has to the top. Also, Poser 4.03 will for some strange reason it will put the rendering progress bar in the bottom right-hand corner of the screen. You may think that Poser is finished, but it is not. You are making a rather large image. So Poser has not locked up but just taking its time. To speed up renders, You can disable background applications. I do this and I have a P4 1.7 with 1Gig of Ram. But, I remember running Poser on a Celeron 366 with 128 mb of Ram. It took patience. Patience is needed for LARGE renders.
