In fact, looks like I posted this last year :)

Listviews handle mouse events a little differently (apparently).  You need
to add:
function fDoNM_CLICK(integer id, atom hWnd, atom wParam, atom lParam) 
    hWnd = fetch( lParam, NMHDR_hwndFrom )
    id = getId( hWnd )
    invokeHandler( id, w32HClick, {} )
    return {}
end function

...and make sure you also modify:

constant kNotifications =
         {
      TCN_SELCHANGE
   ,  LVN_COLUMNCLICK
   ,  LVN_GETDISPINFO
   ,  LVN_BEGINDRAG
   ,  TVN_GETDISPINFO
   ,  TVN_SELCHANGED
   ,  TVN_DELETEITEM
   ,  TTN_GETDISPINFO
   ,  MCN_SELCHANGE
   ,  TBN_GETBUTTONINFO
   ,  TBN_QUERYINSERT
   ,  TBN_QUERYDELETE
   -- added NM_CLICK
   ,  NM_CLICK
         }

constant kNotifyHandlers =
         {
      routine_id("fDoTCN_SELCHANGE")
   ,  routine_id("fDoLVN_COLUMNCLICK")
   ,  routine_id("fDoLVN_GETDISPINFO")
   ,  routine_id("fDoLVN_BEGINDRAG")
   ,  routine_id("fDoTVN_GETDISPINFO")
   ,  routine_id("fDoTVN_SELCHANGED")
   ,  routine_id("fDoTVN_DELETEITEM")
   ,  routine_id("fDoTTN_GETDISPINFO")
   ,  routine_id("fDoMCN_SELCHANGE")
   ,  routine_id("fDoTBN_GETBUTTONINFO")
   ,  routine_id("fDoTBN_QUERYINSERT")
   ,  routine_id("fDoTBN_QUERYDELETE")
   -- added fDoNM_CLICK  Matt Lewis
   ,  routine_id("fDoNM_CLICK")

It doesn't look like NM_CLICK is defined in the latest version, but I don't
have the value handy at the moment...
