I'm getting this same thing too - the fish leave trails of themselves when they are swimming against the background . It's like that thing they used to do on Sesame Street ( well maybe they still do it , but ... ) . The corals do it too when using automatic scrolling .The text from the title screen still shows as well . This is on an old and very basic desktop with Celeron D , 512MB of RAM and a SiS 661FX chipset with integrated graphics . I'm running XP home SP3 . If , as I suspect , this is all because MA is no longer compatible with older and very basic graphics chips , that's okay because that desktop seriously needs to be replaced with something less ante deluvian . It all runs nicely on my 1 1/2yo laptop .
