This happens on browser or downloaded minecraft and i have a mac with the most recent system updates, i have also tried deleting the bin file and repairing my disk permissions

this may be unrelated but WOW wont run either

it seems likely that it is a problem with java but i have java SE6 version 1.6.0_22

other than system update (which i have done) i am unaware of any way to further update my video card driver

i essentially have no idea what else to do
