I've written a package based on the List Manager for putting scrolling lists
in windows and dialogs, and it mostly works.  There is one bizarre bug,
however: if a list is only partly full (e.g. the display rect can show 6 items,
but there's only one in the list) there is usually a "dead" spot in the blank
area.  By "dead" I mean that mouse clicks in that area are completely ignored
by LClick.  Say there's an item selected.  If I click in the dead spot, the
selection won't change!  The spot seems to be the same size as an item, and
it's always a couple of "items" beyond the last real item in the list.  I know
LClick gets called when I click the dead spot, because if I double-click it,
it acts as if I double-clicked on whatever's selected.

Does anyone have any ideas?

Thanks,
