Problem with Multiplicity and Maximized windows

I have a problem with Multiplicity if I use Maximized windows in WOW, then it wont allow me to move as I wish between five different computers with the mouse.
My computers are set up as below
SS
SSM
S=Slave computer
M=Main computer

If I use Maximized windows it allows me to move to the upper computers, but it blocks me from going down. If I turn off Maximized windows it works great, but the game window aint filling the screen. I can press the window maximizer and it works that way. I suppose it works as long as I have the borders around the windows.
Is there any way I can maximize my windows as default when WOW starts (so I dont have to press maximize every time)? And still keep the borders.

I use ISBoxer if that helps.

Changed from Multiplicity to Input Director and it fixed this problem.
