Wide Screen Problem

Hi,

I need your support please. I have patched my client with the wide screen patch.
its working fine but i have an annoying issue as per the below.

Note: I play in windowed mode

Game starts with 800x600 resolution
After creating game it will become wide screen.
I press maximize window to make window bigger then play normally
when i exit the game, it will become 800x600 again
i will create a game again and it will become wide screen but i have to press maximize window again to make screen bigger

Please let me know how to keep it maximized so i dont have to keep maximizing each game.

thanks
