Shogun

I've got a new macbook (with the new intel GMA X3100 card) when I launch the application it doesn't seem to work quite right, the main menu doesn't update very well (only the left half of it show) and the drops that are supposed to come from the mouse stick on the screen leaving a very peculiar pattern, the problems stick through the entire new game interface etc. I Don't know if the actual game works since I haven't been able to get that far Would very much like to play this game so I hope this can be fixed.
