I've had animations of 2,000+ frames (built at 500 frames per time and added, one after the other) with no problem. Unfortunately, Poser can only display a count for the first 999 frames - that's all the space that the counter allows. But, the missing frames are still there, at the end of the animation - it's just that you need to use the arrow to get to them as the counter doesn't go that high. Paul
