(Options) Change Keys

[Janus]

When I go to Options, Controls, Change Keys, and change the keys (or in this case, blank out everything with right mouse click; in column 3); it doesn't save the change, so I'd have to do it every single time I play.

1) I have tried it during gameplay, logged onto a server by pressing F1.
2) I have tried it before logging in, by clicking Options.
3) I have tried before logging in, the logging in; nothing seems to save them.
All of these allow the change to stay only while Graal stays open, if I close it and open it, the keys will revert to what they were before.

I do not press cancel to close the Change Keys window.

I assume this is either a bug, or some misunderstood error on my part.
