Hi!

an interesting question; so i took a look at it.
in my tests neither adding and deleting a new status area icon nor
invalidating the status area window worked.
so i came up with the following solution. (it seems a little unprecise, but
i'll append also one of the attempts i made, to show that the "normal",
more professional trials didn't work.) the one i show after the solution,
which uses TB_GETITEMRECT doesn't work (the message returns TRUE, but the
contents of the RECT are not valid, hence this not very precise variant i
came up with eventually - but try it, i tested it on win2k and didn't
encounter problems, but who knows..., i don't guarantee anything - it could
hide surprises):
=========================================
solution:

HWND hwndTaskBar, hwndTrayWnd, hwndTrayToolBar;
  BOOL res;
 hwndTaskBar  = FindWindowEx (NULL, NULL, "Shell_TrayWnd", NULL);
 hwndTrayWnd = FindWindowEx (hwndTaskBar , NULL, "TrayNotifyWnd", NULL);
 hwndTrayToolBar = FindWindowEx(hwndTrayWnd, NULL, "ToolbarWindow32", NULL);
 RECT rTrayToolBar;
 ::GetClientRect(hwndTrayToolBar, &rTrayToolBar);
 for (WORD x = 0; x < rTrayToolBar.right ; x += 8)
  for (WORD y = 0; y < rTrayToolBar.bottom ; y +=8)
   ::SendMessage(hwndTrayToolBar , WM_MOUSEMOVE, 0,
    MAKELPARAM(x,y) );
==========================================
this doesn't work (at least on win2k not):
LONG lNrButtons = (LONG)::SendMessage(hwndTrayToolBar, TB_BUTTONCOUNT,
  0, 0);
 RECT rButton;
 for (LONG i = 0; i < lNrButtons; i++)
 {
  res = ::SendMessage(hwndTrayToolBar,
   TB_GETITEMRECT,
   (WPARAM) i,
   (LPARAM) &rButton);
  ::SendMessage(hwndTrayToolBar,
   WM_MOUSEMOVE,
   0,
   MAKELPARAM
    (
     (WORD) ((rButton.left + rButton.right) /2),
     (WORD) ((rButton.top + rButton.bottom ) / 2)
    )
   );
 }
