I'm seeing focus problems every few months running WindowMaker, also
in a 2 head configuration.
The focus stick with one window - you can close that one using mouse,
but you still won't be able get focus on another window.
A restart of windowmaker won't help, so far I was forced doing a
complete X restart whenever this happened.
Not shure when it started, likely with an update from an old XFree to
an Xorg release (installed xorg-6.8.2).
