Does the 'maximizer' setting in Keyclone allow for more than one instance of LOTRO to be in the 'foreground' for the mouse/keyboard broadcasting to work?

I guess i'm a little confused as to how it all works. Ideally I want to run 2-4 instances of LOTRO from one PC. Do I need to open more than one Keyclone?

Im checking out the Keyclone website, but most tutorials are for WoW.

Anyone have experience using KC with LOTRO that could explain/tutorialize it a little bit for me?
