I would LOVE to mod BF2 maps, but I can't

When I open up my program to mod a map, it dosn't work.

I double-click 'zeroeditor.exe' to open it.
Then I load the map.
Then when I try to edit it, the mouse skrews-up.

In the middle of the map, the mouse works fine.
When I move the mouse a centimetre (on my screen) away from the middle of the map (not my screen), the object that my mouse is placing / activating/ using moves 2 cenitmetres. Then when it's 2 cm away from the middle the object is 4 cm.

I don't know why this happens or how to fix it, can someone please help me?

That is normal.

I've had the same problem, but it's never hindered me much.

Yeah, you can always move it after its placed by pressing and holding c and dragging with different axes foor right, left, and middle mouse button.

Good luck!

Thanks guys, I didn't know it was normal.

And thank you Master Ben, for the tip

That's normal!? It sure doesn't happen to me! Is there something wrong with my modtools?
