NOONE should have to alter or change anything on their machine to run poser 5....If you meet their minimum system requirements it should work perfectly, if it doesn't stop whining and bitching here and go raise hell at curious labs. You buy sour milk you toss it or take it back, you buy a bad sound system you take it back, demand a refund people!! If they refuse, a few phone calls and they'll change their tune. If poser 5 is working for you, stop bragging about it and get up and on with rendering pics. Stop beating a dead horse, and get on with your lives Enough is Enough
