Just because the PC version of Live 2003 came out later than the XBox and PS2 versions, don't assume that it doesn't have as many bugs as the XBox and PS2 versions. All you have to do is think back to Live 2001 for the PC...the game was literally riddled with bugs, and it came out about 4 months after the other versions came out.
I'm actually having a tough time with this game (a first for the Live series). This problem stems from the fact that I can't seem to get used to the new buttons used for the Gamepad Pro. I find myself turning the ball over at least 25 times a game...and that's using 5 min. quarters!!!
