You were right.
My windows desktop was 800*600, the game preference was 1028*768; so i changed my desktop to 1028*768... but it did'nt worked.
So i putted my desktop back to 800*600 and i did same to the game.. now it works!
But theres still a fu%$#.. i can play only in 800*600 and the graphics are'nt so good that way. i mean i wish i could be in 1024/768 as before on win98se.
If you know the way to do that... ( im about to try the refresh=0 thing)
Thanks again Mister Frag.
