NANO fixed for 98/ME

Please try this ban and po. I found the bug!

And to all:
It was blitz/dx bug... so don't make this same mistake.

I was locking an image buffer at a start of my program, because I only needed to readpixelfast from it. But somehow keeping any imagebuffer locked and not unlocking it before render causes blitz to flip nothing to screen atleast in win98/me. In XP this works fine.

So beware of doing that :)

YAY! It works, it works! It says: FPS: 62. Very cool!
I think that when you kill all of the guys, the camera shouldn't zoom in so much on you. It's hard to navagate that way.
