Query: Can be a pain in the ass for no good reason.

Every time I plug the Stone Plus into the USB port to charge it, Windows Media Player automatically opens and starts playing one of my downloads. That is very aggravating. I just want to charge the player. I don't want to open Media Player and start playing something. The fact that there is apparently no way to control this means that I cannot recommend this player.
