I have had this problem too, recently. It doesn't seem to happen on my desktop, but it does on my laptop. It didn't start happening until a couple weeks ago, though, and I have had the Pro Pack installed since it was released. The little render figure just stops about 3/4 of the way through the status bar - and it will not respond even if you click cancel. If you cancel the program with the Windows task manager menu, it will allow you to save the picture before Poser closes, but the top portion (what the renderer did not finish)of the image is all blurry lines. Any information on what could possibly be causing this would be greatly appreciated. Thanks!
