Linux (4.0212): Key mapping
 

If I try to map a key using F3 options, the REMAP dialog comes up and the keys seem to remap (i.e. if I remap the "Item Menu" key, each keypress changes the small text at the top of the "D"), but the remap dialog does not disappear and I must close Graal to complete the key remap.

Ah thats weird. It's working when you open the options in the start screen, but in-game its bugged, will fix it soon.
