See my previous replies. You can't do that without using DXGrab.

If you wait for mouse to be withing 2px of the border before you warp:
1. You will loose part of the long pointer motion (say 100px while pointer is
10px away from the border). This will be felt like "sticking" mouse in action
games.
2. In 99% cases you will loose the pointer itself (it will go off the Wine's
window). This means number of bad things. The biggest one - Wine won't be
receiving any pointer movement events at all. And nothing will be warping that
pointer.
3. You still not solving the problem with "edge-scrolling" used in some games
to scroll screen when you move mouse "past the edge".
