evdev and mouse

[Кириченко Георгий]

Hi! Sorry for my bad english...
I am have some problem:
I am use evdev driver 2.3.2-6 and xserver 1.7.6.90 from Debian sid with A4Tech 
mouse model X-710FS. And when mouse button was pressed or released the evdev 
driver before key event post move event to Xserver with no changing coords.
I am try debug driver and see: moving event has no X or Y moving, but has Z 
moving (15 pixels at every time).
And i am have random selection when press left button, in some applications 
(change sorting in krusader) mouse can do "Double Click"
I am have do this: add filter:
if (!(v[REL_X] || v[REL_Y]))
    return;
in EvdevPostRelativeMotionEvents and all work properly.
But i am know not: this is hardware bug or no, and is my fix right way or no.
With another mouse i am have no some problem, and no problem with earlier 
version of xorg.

Xev output in attach.
