This has always been a small problem that only happens once in a while, but after I upgraded from some old daily build (August-ish 2009) to the 100315 build, I have been trying to put up with it randomly skipping ahead to the next track while playing. But I've figured out that it only happens when I have bookmarking enabled. Well, this is a real pain when I try to listen to podcasts. Either I can try to remember to stop it every few minutes to save a bookmark just in case it decides to jump ahead, or I can just disable bookmarking entirely and figure it out manually. Neither of which are fun.
I always turn on the lock switch when I throw it in my pocket, it's become a habit (to the point where the rubber backing has been worn off around the power switch). I see no consistent pattern to this skipping, just that it happens whenever, sometimes while I have the screen on I watch it happen, other times while it's locked. Any insight would be nice. Thanks!
