The trouble is I don't have a machine here that I can replicate these  problems on so I can't very well diagnose them.  As far as I can tell it's  a problem with the machine's DirectSoundCapture drivers and the only thing  that's different between machines that exhibit the trouble and the ones  that don't is that the machines that work all have DirectX 7.0 installed on  them, so you might want to try that.    Come to think of it, maybe all the broken machines are Dell laptops. -jonathan (j.c.f.)   /"\\   \\ /    X  ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL   / \\    Not every question deserves an answer.                                                 - Puvlilius Syrus                                                         Senentiae
