The Bluetooth mouse causes music skip.

When playing music or streaming video through external BT speakers and the BT headphones, as soon as I touch the sides of the mouse the music starts studdering and skipping. If I disconnect the mouse and use only the keyboard to control the iTunes or the YouTube streaming everything goes back to normal. Normally disconnecting the headphones helps too. What is wrong with the mouse?? Very annoying, this is happening at least 5-10 times per day.

Is there a solution, besides getting rid of the BlueTooth mouse and getting the third party one?

Thanks!
