Derek,

Maybe this is not related but I accomplished incremental adding of list 
view items with the following event handler:


procedure ResultsLV_onEvent ( int iMsg, atom wParm, atom lParm )
    atom rtn_code, pos
    if iMsg = WM_VSCROLL then  
        pos = sendMessage(ResultsLV, LVM_GETTOPINDEX, 0, 0) + 1 
        if pos >= last_rec - 20 then
            loadNextBlock()
        end if
    end if    
    if iMsg = LVM_SORTITEMS then
        returnValue(True)
    end if
end procedure
onEvent[ResultsLV] = routine_id("ResultsLV_onEvent")

This way you don't have to draw the scroll bar and it also handles the 
sorting issue (well, not really handling it, just ignoring it).  Maybe 
this would be a routine to include in Win32Lib?
