Not quite sure if this has been reported yet:
I had this one mp3, which was about 60 minutes long, at minute 40 I pressed the >> button to skip a part, but after releasing ( skipped about 1 minute ),
I actually found myself a few minutes behind my last position.
After that, it seemed to be working again. I guess it has to do with how long the file has been played.
Bitrate 128, no VBR. MediaMonkey information says, it’s seekable.
