Following up to myself, but here's the error (kernel/program/.c) lines
255-260:
case KEY_ONOFF:
// works only if no programs are running.
if(nb_tasks<=3) {
killall(PRIO_HIGHEST);
}
return 0;
^^^^
This should be 'break'. The way the code is now, pressing on/off
while anything is running exits the key_handler() thread, and of course all
the keys except for "View" stop working.

| (...) If ON/OFF is desired while programs run, just drop the if. If ON/OFF isn't to work while programs run, it has to be this: if(nb_tasks<=3) { killall(PRIO_HIGHEST); return 0; // killall doesn't kill self } break; What does standard firmware do? (...)
