How to have two windows in focus at the same time??

Hello,

I need help doing something. I am trying to troubleshoot my PS3 controller on Windows 7. I play my games on the TV, so when I turn around it lags a bit. Now, I am not asking for help in this, all I need help in is:

When running multi-monitor, with the TV the main screen and the laptop as the secondary display, I am running the game on the TV, and on the laptop's screen have the controller properties screen where you can test the game controller and see if its buttons, sticks, ect work. So, with the game running on the TV, and the controller window on the laptop, I navigate through the game with the controller, it works fine, but it doesn't report it on the controller properties windows. It turns out that I have to have that window selected/in-focus for it to report the controller's key presses, or it doesn't work. So what I am asking is, how can I make that window in focus while running the game?

Thanks.
