How can i do this ?

[Dice Man]

As well as my 4 table (tiled) set-up on my dell, i've also got 2 tables cascaded on another monitor.

Are there any scripts/software that will allow me to "cycle" between the 2 cascaded tables? This will have to be done with either left or right mouse clicks.

Having to continually click on the top/bottom of the cascaded windows is a pain.

I know that Alt+Esc and Alt+Shift+Esc allows me to cycle through the taskbar windows, but this cycles through all of them. How can i just cycle through the two i need?
