I'm SO pleased that M has finally found this problem. I originally posted this issue on 31 July, 2008 (did a search to find the thread). I sure hope they update the 568.2 beta code (v2.5), rather than the officially released (v2.12) code - it is sonically far superior.

Thanks all for hanging in there with me!
