Love Quicksilver - especially when it works with iTunes. But it seems very inconsistent.

Usually, I'll type in "music library", then type the name of the song until QS finds it, hit return. Sometimes it then opens up iTunes and plays it, sometimes it just opens iTunes with nothing, and other times it opens itunes and plays a completely different song!

It does the same thing when I start typing a playlist, type the song..etc.

Anyone having this problem or know how to fix it? Thanks.
