Hey, this has probably has already been said, but if you go far into the future, the orbits of alot of planets and moons get really messed up. i've seen it where the moon is halfway into the earth! This isnt really a problem for me because i dont really go that far into the future very often, but I thought that maybe someone should know to fix it. I'm not sure what my graphic card is, so i guess if that has anything to do with it, it my be a little hard recreating the prolewm. I can tell you this though, i got this computer around october of last year, so its about 3/4ths of a year old, and if this helps at all, its a dell 4300.
