i would imagine most people use keyclone's built-in maximizer to layout their wows. no overlapping required. keyclone also helps get the most out of your hardware by allowing you to set your fps per wow (under keyclone/setup/command editor)

here's a sample of a 4 wow layout on one screen:

or 5 wows across 2 screens...


there are many possibilities. check out the sample maximizer layouts on the main keyclone site (link )

and of course, if you're still a bit fuzzy... just drop me a PM and i'll see what i can do for you.
