Hi,

I've been trying to set a custom key in the preferences so that the player will escape when I hit the exit key. However, when I hit the esc key in the 'key' field ... it closes the preferences window.

Is there any file I can manually edit or something along those lines?
Any help would be greatly appreciated.

Right click the key field and choose "Esc" from the popup menu to assign a shortcut to the Escape key.
