G'morning Nicodemus and welcome to the forums!

start one wow... go to options/video ... make sure it's in windowed mode.. then exit.

after that, make sure to create 3 keyclone commands to start your wows and put them in the regions. remember to specify the region names exactly as they are spelled in the layout ( ie: region1 not 1 or Region1 )

oh... and make sure to CHECK keyclone/setup/maximizer/enable-maximizer

if you have any other questions or comments, please feel free to drop me a note.
