I use this mouse under archlinux x86_64 with 3.2.8-1-ARCH kernel.

I have some problems to select and then paste with the wheel-click in some applications like konversation, not in a terminal nor an editor.

I don't know if it's a hardware problem or a software one.

When I see what's happens in xev, the output is different compared to another mouse

A demo of the problem when I use konversation (IRC) : http://www.youtube.com/watch?v=lhmr92M7NCc

I tried to modify the button map with xmodmap like this with no success (one at a time) :

xmodmap -e "pointer = 1 0 3"
xmodmap -e "pointer = 1 1 3"
xmodmap -e "pointer = 1 2 3"
xmodmap -e "pointer = 1 3 3"
xmodmap -e "pointer = 1 4 3"
xmodmap -e "pointer = 1 5 3"
xmodmap -e "pointer = 1 6 3"
xmodmap -e "pointer = 1 7 3"
xmodmap -e "pointer = 1 8 3"
xmodmap -e "pointer = 1 9 3"
xmodmap -e "pointer = 1 10 3"
xmodmap -e "pointer = 1 11 3"
xmodmap -e "pointer = 1 12 3"
xmodmap -e "pointer = 1 13 3"
xmodmap -e "pointer = 1 14 3"
xmodmap -e "pointer = 1 15 3"
xmodmap -e "pointer = 1 16 3"
xmodmap -e "pointer = 1 17 3"
xmodmap -e "pointer = 1 18 3"
xmodmap -e "pointer = 1 19 3"
xmodmap -e "pointer = 1 20 3"
xmodmap -e "pointer = 1 21 3"
xmodmap -e "pointer = 1 22 3"
xmodmap -e "pointer = 1 23 3"
xmodmap -e "pointer = 1 24 3"
xmodmap -e "pointer = 1 25 3"

Any clue ? I would like to avoid buying a new mouse just for a paste problem.
