I recently installed Parallels 4 (Build 3844), on Mac OSx 10.5.8, running on a new MacBook Pro with 4 GB RAM. As I navigate Windows in XP Pro (Sp3) using Windows Explorer, clicking on folders initiates speaker hum. This hum goes away after about a minute, but returns with further windows navigation. Has anybody else experienced this and more importantly, any ideas about making it STOP? ;-) SL
