Thanks for all the replies.

I found that if I put a pause in between each maximizer.exe in my batch files, that they would stay maximized. Like this:

[code:1]start e:\wow\maximizer -D 1
pause
start e:\wow2\maximizer -D 2 --margin 0,512,0,640
pause
start e:\wow3\maximizer -D 2 --margin 512,0,0,640
pause
start e:\wow4\maximizer -D 2 --margin 0,512,640,0
pause
start e:\wow5\maximizer -D 2 --margin 512,0,640,0[/code:1]

I also found that if I don't pass through the mouse activity, that I don't get stuck on the 2nd monitor and I'm able to use the mouse on the 2nd monitor.

I still haven't figured out how to use the Maximizer built into keyclone. Is there documentation somewhere? There doesn't seem to be. Does it support multi-mon? How do I start WoW via Keyclone?
