Cubase 6 Mac : Audio Fade out problem (bug ?)

Hello, on MacPro 2,8 G (2010), found a problem with Cubase 6 :

  • go in Audio Editor with any audio track,
  • try to fade out Audio,
  • get a big terrific noisy wave, every time

Sorry for my English… Thank you

You might get better support in the Cubase 6 section. This is for C5 and before.
