Hi Joerg,
I tried this because I have problems with my buttons not working right,
e.g., when down arrowing, sometimes it jumps into a folder or menu, as if I
had pushed the right arrow. It usually happens with several down arrows in
But I installed your fix, and I cannot enter the menus with F1.
Did I do this wrong?
I unzipped it, and copied the two files over onto my jukebox, as if they had
been part of a regular daily build.

Subject: unreliable buttons? try this:

Several people reported unreliable button detection by Rockbox, sometimes
there are misinterpretations. You can stop reading if you don't suffer from

I have added a kind of "debouncing" to the button code. Now, a button is
only valid if the analog port reported several stable readings within a
certain "corridor". Please test it and report if this is an improvement. The
corridor may be too strict, causing dead buttons. So try the .ajz via rolo
first, flash later, or you need the F1-start. ;-)

The files are here, grab the .zip for your model:
Source code is also there, for the curious.
