WMP 11 Click a song, it plays the one below it...

My WMP 11.0.5721.5268 has started acting funny... if you are looking at just
one album and click a song to play it plays the one under that... ie; if you
wish to play the first song you must click the last song.
In a large list (like browsing newly added music) if you click on a song it
will play something from two or three albums down the list.

Also, I notice that if I start dropping songs in the playlist it will play
the first thing I drop (like normal), but then when you go to drop more songs
in to add to the playlist it puts those songs above the song playing and not
below like it normally would.
WMP still has full functionality but the above issues are highly annoying...
It might really be time for mac maybe... help!!!!!!!!!
