ive had this problem for ages.. i read others threads and it definetly works..

okay im running a nvidia 7800gtx, i changed all setting to 8xaa and 16aa etc for my games.. then my limewire went blank when starting up, i changed all setting back to their defualt and limewire starts up..

just passing on the info.. it was really fustrating restarting and installing all diff versions and java, that is the only fix that worked!!!!!
