I thought something was wrong with my radio. I would switch between slacker songs and it would switch to the radio. I realized last night if I hold the button it switches sources, hold the back button and it goes back to the last source... ie. Slacker to Tunin Favorite to Radio.. I guess I was holding the skip button too long and thought the changing sources was a bug.. I havent seen this mentioned anywhere, but then again I havent read every update thread either.
