I’ve been using different versions of flash for about 6 years now, and have only recently encountered this problem. I find when I’m working on a large animated movie project which uses a lot of motion tweening, the symbols seem to vanish from the stage when they are supposed to be moving. They will be visible at the keyframes where I have positioned the symbol, but where I have placed the tween, they don’t show up at all. The only way I can make them visible again is if I keep going back into symbol editing modes and replaying the timelines for the various symbols. But evetually the problem will arise again. Has anybody else had this problem with Flash 8, and does anyone know how to fix it?

Thanks.
