Matthew,

Could you explain what you mean by a "hit test"(ie, hits what, since no
index is returned), & how to use LB_GETITEMRECT and LB_GETTOPINDEX for the
hit testing?  (Are you talking about getting the size( y extent) of the
listbox, the y position of the right-mouse click in the listbox, the number
of items in the listbox, the y size of each item, & then compute which item
was clicked on from all that??)
