URGENT ! WPF screen resolution ?

Hi all ..

I had my program written in the Com's resolution of 1920 x 1200 it works well and able to see all of the controls .

However when i change to my laptop with a resolution of 1366 x 768 come of the controls were out of the screen.

Note that the WPF screen is able to maximize to the laptop's screen but the controls were hidden out of the screen.

Anybody know what happen?

Thanks alot .
