Hi Steven ,
(the link to the first CUE sheet didn't work because of a typo, missing space before "and...").
Anyway: I just did one final test and tried one more thing (I had a gut feeling about this): I disabled my WinAmp and VST plugins and guess what? Yes, exactly: with those disabled the bug does not occur. But please read on: no matter which plugin I use: they are all causing this bug.... No matter if it's a VST or Winamp plugin... So, could this be a bug in the plugin support of MB?
I just sent you a link. Thanks again for your time.
