Notice that "Alanis Morissette - All I Really Want" appears twice, once at spot 14 and again at 34. Within the playlist editor, I select the one at spot 34 and hit Q to play it next, and the song at spot 14 is selected next in the queue list. I hear "All I Really Want" is played next, but then it continues on to Dave Matthews instead of Griffin House.

I have replicated this on 3 different machines, all running Windows XP sp2, clean install of Winamp 5.32. I don't know which version of JTFE I am running, how can I check?

If this is a feature, I'm sorry for reporting it as a bug but how do I turn it off?
