The default button mapping is:

1 left
2 middle
3 right
4 wheel up
5 wheel down
6 extra button 1
7 extra button 2

So, I would naively expect the 4th button on your device to be extra button 2,
and reported by X as button 7.

I borrowed a 5 button mouse for some brief testing, and as far as I can tell
the button mapping for extra buttons 1 and 2 is working correctly.

If you'd like to try to investigate this a bit further, it would be helpful if
you could:
* Download the latest snapshot built with debugging enabled from [1], and
install it using the instructions 'Preparation (alternative approach)' at [2]
* Run it using 'WIN_DEBUG_MESSAGES=1 ./XWin -logverbose 3 <your usual XWin
options, -multiwindow for example>'
* Look at the debug output from XWin and see what Windows messages (if any)
are reported when the 4th button is clicked

(As a separate issue, it also looks like this mapping may not be ideal, as the
default on linux is for 6 and 7 to be used for tilt wheel left and tilt wheel
right, and extra buttons as 8 and 9, and there are applications out there
which can use that...)
