Using keyclone with The Lord of the Rings online

My Keyclone runs great with WOW. But when I started using it with other games, I ran into an issue where only the active window got the keystrokes, not the ones in the background (not minimized). Specifically, I was trying The Lord of the Rings online. The keystrokes would only get passed between two active windows of two computers. The other instances of the game, which were running in the back, were not getting the keys. I think Windows could only have one active window at a time. So I am stuck with running only two clients with two computers. I wonder if this is the limitation for keyclone right now as it might have to do with the way lotro launching itself.

This was not an issue with Wow as all windows would get the keys regardless foreground and background.

I'm not positive but I believe that what you are describing is an issue with LOTRO, not Keyclone. I'm pretty sure that LOTRO will not accept any input if it is running in the background.
