Whilst playing on my mac G5 am finding the game sticking everytime an advert pops up top left... but when i'm on my pc laptop at home its fine, can this problem with the mac be resolved at all, oh, also frequently the target used to shoot goes and am left with just the curser. Just thought i'd ask see if any other mac users are having this problem as its impossibe to get a decent break using a mac lol...

cheers!
