One of my problems with clonekey to date is that the more windows I have in clonekey for broadcasting, the more chance I have that the keys will not be broadcast. For example, with 2 characters, no problem it seems pretty flawless in sending the keystroke to both windows. When I have 3 instances going I run into the problem more often. Yesterday I played 5 mages all level 1 just to see how well it would work, and basically every cast I would have to hit the cast button more than once to make sure they all casted. I run all instances in windowed mode, and I get pretty decent fps when I have all graphics turned down which is how it is set up. I use a wireless keyboard, but im not sure if that has much to do with it (who knows, maybe it does).

and to Alphaquam, I would be more than happy to donate some money to help out with the development if you were to take it on.
