it only stopped cause i made more adjustments to the window
ive got two 21 inch monitors
one set at 1600x1200 the other at 1280x1024
make the window very short and lengthen it across both screens. then i position my mouse at the far left up high corner. if you make it too short to start the shark freaks out and does figure 8's
also, if you get the shark far enough ahead it doesnt matter how fast you go. the divers only spawn in the playing field and the shark isnt on the field any longer

edit : changed res from 160x1200 to 1600
edit 2 : it appears to only freak out if you make the window too short too fast. going slowly and keeping the shark on the screen ive managed about a quarter inch by 2 feet wide viewport.
