Break the recursion. Something like this:

static  bool   recursed = false;
OnMouseMove()
{
    if( ! recursed )	/* stop recursion */
    {    recursed = true;
         if( NewMouseCoord != DesiredCoord )  /* stop infinite loop */
        	SetCursorPosition( DesiredCoord );
         recursed = false;
    };
}
