This morning, I was listening to the tuner on my way into work. When I got here, I brought the player in to use on AC in the office, and it booted up in MP3 mode, as usual. But the Seek Tool remained resolutely stuck at zero time, even though I got music and the full UI.

Pausing and unpausing had no effect; neither did changing tracks (with or without the Seek Tool showing). I tried warm booting ('q' on serial) and even power-cycling to no avail. Eventually, what worked was to change sources to Aux and back again.

When I got the tool back again, I checked to see whether any data had been gathered, and none had, though it didn't appear that any damage had been done to previously-gathered tracks.
