Rockbox

Version CVS-060418 on H120 w/LCD-remote
Medium severity since it can be solved w/o reset and avoided by being careful, but it's easy to fall into, very user unfriendly and surprising at least to neophytes.
Targets: I don't know if that happens on other platforms, but assume at least the H3xx may behave similarly with an LCD remote.

Using the H120 LCD remote control, it is easy to enter some menu and have the remote become completely unresponsive. Backlight still works, but that's all
To solve the problem, one has to pull out the main unit and use it's buttons.

This behaviour is completely unexpected (has Rockbox crashed?) and annoying (keeping the player in the backpack or pocked is foiled).

Even if you use the H120 to switch to these menu points, the remote becomes unresponsive.

and probably many plugins and a few other menu entries.

I believe:
* No action on the remote may cause the remote to become unresponsive.

Hence, to solve, I see at least the following possibilities:
* gray out/block/remove the offending entries from the LCD remote.
* show a "Sorry, that doesn't work on the remote, press STOP to back out" when these entries are selected, and make STOP work.
* build an remote LCD capable version (e.g. the virtual keyboard could work with scrolling on the screen)
* switch to an alternate version (e.g. the simple & and advanced EQ settings instead of the graphical one)
