Hi, i've installed new RTM and everything was good since i ran winamp. Sound stutters and cuts while i'm doing something "bigger" on the screen i.e. "Run as administrator" privilege window and when changing resolution... I've checked this and some ppl reported to have the same problem. Do you have any solution for this?
