At first I thought maybe that you had the "Motion Blur" on. But that option is not available when creating a SWF. SO I guess I would need more information on what is exactly blurring. Perhaps you can post a frame so we can see what it is looking like and then we can better try to figure out what's happening. One problem may be the you've set the Flash settings to "Quantisize" every frame. This eats up memory and may cause blurring since it tries to create a new palette for every frame. James
