I want to get my fourth button (which for arcane reasons know to
itself Linux thinks is 'button 9') to do what, by default, a double
click of button 1 does.

The *horrible* mess of using an application to 'catch' button 9 and
simulate clicking button 1 twice to do this has stopped working on
Xubuntu 10.04 (it used to work OK on 9.04 and 9.10). I've decided
that the only sensible way to do it is simply to tell the system that
I want the actions normally associated with "Double Click Button 1"
should instead be associated with "Click Button 9".  Simple, if I can
find where this association is effected.
