turn off the 'focus follows mouse'.. wow has a bug where it will jump/reposition the mouse if you are in windowed mode.

just run a wow.. no keyclone... put it on your 2nd monitor (or anywhere to the right)... put a browser or something to the left of it...
start quickly clicking the wow window... and your browser will pop to the front.

that would be the wow bug.

and it focus follows mouse, when you click ... the cursor jumps... keyclone gets that.. and pushes focus to the new window..

i may have a work around. working on it...
