I have a Sansa Clip+ and installed Rockbox 3.13 using the Rockbox installer.
Everything works fine in terms of the menu navigation, settings, playing audio, etc.
However, in the WPS (Playing now) I cannot use any of the left/right/pause-play/sub-menu buttons (essentially the up/down/left/right circle around the main button).
To clarify, the buttons react in the normal menus and they also react to long-press, but not to short presses.
As such, I cannot pause/play, forward to next song, or previous song, etc.
When installing, I used firmware 01.02.18.
Then, upon finding this issue, I downgraded to 01.02.16, but the problem is exactly the same.
As I didn't see anybody else with this issue, I fear that there might not be much help. But I thought I'd try nonetheless, as I have been a long term Rockbox fan.
Thanks for your assistance.
