Ok that a pain to alway check. I got it working.

just tried it and it works for me, i had it set to entire library.

In the final version it is not searching for me. I reinstalled and it worked normal then today it back to not doing anything when I type in a artist name etc. my music is on another pc and it adds all the music so I don't see a problem and if I manually look it up in the tree and click it plays.

No issues in RC 6 which I am thinking of going back too.
