lets try to trouble shoot here.

in keyclone, do you have all four windows added to your keyclone?
if you are broadcasting your keystrokes, when pressing "O", do you get your social tab to pop up? Press "P" and see if all your spellbooks pop up. press "M" and see if all your characters show their maps. "Shift+B" and see if all your characters will open all their bags. if they do, and you still have problems with other keys like spells and things, perhaps your macros or keybindings for your other two WoW's need to be fixed.
