I have uploaded a "Prerelease" of LBGUI, which does not yet include the header, but the source code of the last demo, an other, smaller demo including commented source code, which also shows that multiple selection is now possible, and that bitmap cursors work (although you need a little workaround for the hotspot), and the manual of LBGUI.
