I've never seen this before!
I load a config that I have made.
I shut down.
I power up.
Now some settings - some which I haven't messed with in a long time - have changed to the default values. My WPS stays the same as before.
iRiver H120 - r15844-071128, and two days earlier as well.
Any clues??
EDIT: Here are some of the settings that changed:
volume: -25
repeat: all
backlight timeout: 5
volume display: graphic
scroll speed: 9
scroll step: 6
scroll paginated: off
show files: supported
EDIT again:
SOLVED!
I think this started after I had to reset settings manually.
This to overcome a crash at every restart. RB was trying to resume the last seconds of a song (a known bug).
Before I tried to install an earlier build I deleted the old .rockbox directory - haven't done that before.
Then the problem disappeared, no matter what build I used.
This told if someone else gets problems like this...
