I'm glad I'm not the only one with the Audio Preview Bug in the Media Browser.
I haven't noticed the problem of playing audio tracks when you've added them to the Audio CD window however.
This seems to work for me without problem.
I will report the bug to the link you give.
I think I will go back to version 11.1.
What is the best way to do this?
I have the 11.1 update installer.
