using a mac eh? that's probably why. didn't you know that steve jobs hates asians? Mac OSX is obviously racist.
ok no but for reals...i was about to give you some help but then i saw you had a mac...ugh. buy a PC j00
do you have the asian language pack for it? im not sure where to get it, but it's a little app (like the language bar in XP) that lets you switch languages. i dont even know what it's called, all i know is that all the macs in my japanese class have em.
lastly, you could try a different browser.
