first, make sure your wows are running in windowed mode. (in-game/video/windowed mode)

that should help get your wow maximizer the way you want. there are some threads that talk about the various settings.

using keyclone, you can set up a command for wow, configure a region layout, and then enable maximizer. once that is configured, launch your wow from the keyclone edit box on the main screen (to the right of the connect button)

this may help:
