[Pharo-project] How difficult is to fix this keyboard input issue?

Hi! In order to have a decent keybinder/keymapping/shortcut package, we need to fix this crap: http://code.google.com/p/pharo/issues/detail?id=3748&q=events&colspec=ID%20T... :) I don't know if someone can take a look. Maybe it's easy to fix, maybe it's not :S. Maybe someone can just give some directions :). Thanks! Guille
