I manualy go in and change the priorty to normal or above normal and it will run fine, but than after a minute it resets it's priorty back to below normal. how do I fix this orchange this so it always runs as a normal or high priorty item SO One of my programs, A video Game, runs on normal priorty intill it gets to a certain point and than it automaticly changes to Below normal priorty. this cuases the program to lag and get very very bugy.
