Keyclone PiP obscuring WoW interface

I'd prefer to use the PiP setup under Keyclone's Maximizer but it seems that any place that I put the window, it obscures something. There's no way to temporarily turn off the window and no way to make it go behind the Main WoW window. It's a bit frustrating.

Right now, I'm doing a Horizontal Split but I'd prefer to use PiP if I could interact with the UI elements underneath it. Any suggestions on doing so?

Hmph. There is no confused smiley as an icon for this post.
