As reported on http://marc.info/?l=openbsd-ports&m=129651693706010&w=2, when one configures action buttons plugin as two buttons, the plugin shows two very tiny buttons one above the other when panel is horizontal, and one beside the other when panel is vertical. The alignment of buttons should be inline with panel orientation. Had a look at xfsm-logout-plugin.c, and i don't see where to fix that.
Reassign to panel, as actions plugin comes from there now..
