If you use either bbpager or bbkeys, then you will need to have AT LEAST
these versions:

bbpager 0.3.0	from http://bbtools.windsofstorm.net/
bbkeys 0.8.3	from http://bbkeys.sourceforge.net/

If you use anything older than that, they will not work with Openbox.  Why?
The old "Blackbox protocol" used by Blackbox 0.60.0-alpha had messages,
properties and the like prefixed with _NET, which is to be used by
the new KDE2+/GNOME2 window manager specification.  It was decided to keep from
polluting the namespace and everything changed to _BLACKBOX.  When the change
was made, bbpager and bbkeys (as well as other tools, I believe) had to be
updated to understand the new protocol.
