I'm actually working on a better version of CloneKeys for the Mac. I have some features like blacklisting keys per app. However, I've noticed key sends are just lost sometimes when I have three instances of WoW open. With two instances I don't get any problems at all. I'm not sure if there is a system resource problem or a problem with the APIs. I have some ideas on how to remedy the problem, but we'll see how well they turn out. I haven't experienced the delayed key sends though.

Also working on networking at the moment to at least provide a work-around for running multiple instances on a single computer.
