I have noticed when i have some filters on the F isn't appearing where it should.

Also sometimes the player is not remebering where it was in the playlist:

Yeah I think I remember that happening a lot with the previous beta.. I havn't tried it since. But having the filters on always made the player forget it's possition... as if it calculated it's possition as if the filter was off or something..

(took me a few reads to know what you were talking about)
