Thanks... It really helps to know one is not alone...      :-)

BTW, when a Poser scene is on the limit, you only can render it after restarting Poser. Poser never cleans memory before rendering or after finishing a render; So if you make the same render twice, the first time it will work, the second it will crash. I always restart Poser before rendering. Helps also not to forget to save le latest version of my scene...
