when i sort tracks by album, i expect that winamp sorts track from the same album by the tracknumber which in most cases works fine. however it doesn't work every time: sometimes it's only the second track is shown before the first, sometimes all tracks are mixed.

this effect doesn't appear completly random, as every album is always sorted in the same (correct or incorrect) way and it doesn't matter if i view the album alone or together with others.

any idea what could cause this behavior and how to get rid of it?
