howdy wolf and welcome to the forums!

to use both screens, go to keyclone/setup/maximizer... layout your main screen then change your display using the display selector in the lower right. then layout the regions on that display. note all the region names you are using. then go to the command editor and create 1 command for each wow you want to run, specifying the appropriate region for each as you go.

i hope that is what you are looking for. if not, please let me know.
