Liski,

It sounds like Sharp is having the same issue as I reported a while ago.

In which let's say I would like to move ERT to be positioned before Alpha channel.
I move it, and save it just as the instructions state, and when I exit the menu, ERT has stayed where it is, and one of the Arabic channels, say channel 6 has moved to the position right after channel 72.

It's really strange.
