I have a multi button mouse.
Wanted behavior:
Clicking anywhere on a window with the thumb button (mouse button 6) to
pick that window up for ManualPlacement. Moving the pointer to a new
location and then clicking the thumb button again to put the window down.
In my config file, I have the following:
Mouse 6 A A Move
This is working, exept that pressing mouse button 6 a second time aborts
the move instead of placing the window.
I suspect the solution requires me to edit the fvwm source code. But I am
not sure where in the source this lives.
