I have a Radio Button with a saved playlist titled "Was Playing". I frequently save what I was just listening to before doing something else with Playing Now. When I'm done, I press the Was Playing playlist button and I'm back to where I was. I've been doing this for years.
Something like 1.5 generations ago (in MC22 perhaps?) a bug appeared: The playlist works as normal; it starts playing the first song when I press the playlist radio button. When I press the space bar to pause the music, it restarts from the first song and DOES NOT PAUSE. The spacebar restarts the playlist from the first song. However, if I manually click on another song to play it, then press spacebar, it pauses as expected.
I noticed something today which provides a new clue: I pressed Was Playing, and waited for a song to play. Then I pressed "control-R" to reshuffle the playlist. Finally, I pressed space bar. Now, it started the playlist over, but in the old order! It reloaded Was Playing and started it from the beginning.
As I said, I've seen this behavior for more than a year. It's entirely reproducible.
If you need any more details, please ask.
Thanks!
Brian.
