[chuck-users] Horrble noise bug?

Hi folks, I'm working with some guitarists who are using my Guitar Zero practice program, and one of them reports the following problem: Hi Inventor I just tried the new version and the letters work perfectly on the start screen. Congratulations! ;D However, when I tested it I didn't actually connect the microphone, just checked the select game screen and [b]every time[/b] after I close miniAudicle my computer speakers + headphones just make a horrible buzzing noise and I have to restart the PC. Any ideas? A Is this a known bug? The user is running Windows XP. Any help or ideas would be appreciated, thanks. Les (Inventor)
