The end of last played note while closing the file is heard when opening another file

A strange but really minor issue... I can easily imagine it's specific to Windows. Using Beta2 on Win7.

I used these two scores
http://musescore.com/user/70409/scores/570026 and
http://musescore.com/user/44766/scores/68520

(1) Close all your opened scores (it doesn't occur if another score is opened)
(2) open the Händel score
(3) start to play it (space ) and close the score (mouse) immediately while it plays the first Half note.
(4) open the Indiana Jones score, I can hear the very last end of the note of the cello that was interrupted at the closing of the Händel score, as soon as the Indy file is opened&displayed.

As I said, it's not very important but it just made me smile because it was so unexpected... ;-) I know you will rather curse, "sh*t, yet another issue", sorry.
