Strange problem since WoW update

EDIT: Never mind, this seems to have been a temporary glitch. Restarted Octopus sorted everything out.

I'm seeing a strange problem since I updated my 5 multibox installs to 3.0.2 and I have no idea how it could possibly be happening, but here goes:

In Octopus, I have defined a key list to NOT pass W,A,S,D,Tab,Escape,Numlock to all instances of the game.

No matter what I do though, these keys are now broadcast to all running WoW instances.

Broadcast keys is on, Passall is off, Bypass is off. Normally this would result in only the focussed window receiving WASD, but now they all do.
