Tony,
below is the corrected routine from Matt Lewis. His original routine had a
couple of bugs.

--/topic ListView Control
--/proc changeLVItemText( lv, item, column, text )
global procedure changeLVItemText( integer LV, integer item,
                                   integer subitem, sequence text )
    atom hWnd

    subitem += 1
    release_mem( lvitem_data[item][2][subitem][1] )

    lvitem_data[item][2][subitem][1] = acquire_mem(0,  text)
    lvitem_data[item][2][subitem][2] = length( text)

    hWnd = getHandle( LV )

    -- invalidate all of the current window, and clear it
    VOID = w32Func( xInvalidateRect, {hWnd, NULL, 1} )

    -- trigger an immediate paint message
    VOID = w32Func( xSendMessage, { hWnd, WM_PAINT, 0, 0 } )

end procedure
