Hi. I used to enjoy Bejeweled on my old pc running win 98 but since i bought a new pc a Carrera 253 cb running xp, mitsubishi diamond pro monitor Bejewled works but flickers. I have noticed that there's 2 fine lines running horizontal on screen about a 1/4 of the way from top and bottom. Tried d/loading game again but same results. Any sugestions please ?
