How can i fix my resolution?

Hi crossfire,

i've recently reinstalled my ET but now my resolution goes all bananas.
My screen has resolution 1440*900, but i'm used playing ET with a reslution of 1024*768 and then turn it to full screen. That way ET normally got stretched to the my full screen.

I used to just need this:

seta r_mode "-1"
seta r_customwidth "1024"
seta r_customheight "768"
seta r_fullscreen 1

But now, instead of going full screen, ET just shows a playable area of 1024*768 pixels and the rest of my screenborders around ET are black.

Anyone can help me fix this?

btw: The internet is full.
