Hello Oleg;

I took your reply as a hint and wrote my own OnNotify() function. After changing the flag for the second parameter of SetWindowPos to HWND_TOPMOST it works as expected. Here are my small changes in my treectrl class function OnNotify() (perhaps this changes should also go into your CXTReeCtrlBase class:

if (hWnd != NULL)
{
// make sure the tooltip is at the top of the "Z" order, otherwise
// it will appear behind popup windows....
::SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE);
}

Hi Oleg;

This happens with the CXTTreeCtrl! I'm not using the CTreeCtrl. I create the control in this way:

Am I missing any necessary style?

It is known CTreeCtrl problem.

here is code we use in CXTTreeCtrl to fix it:

BOOL CXTTreeBase::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
NMHDR* pNMHDR = (NMHDR*)lParam;

switch (pNMHDR->code)
{
case TTN_SHOW:
  {
   // get a pointer to the tooltip control.
   HWND hWnd = TreeView_GetToolTips(m_pTreeCtrl->m_hWnd);
   if (hWnd != NULL)
   {
    // make sure the tooltip is at the top of the "Z" order, otherwise
    // it will appear behind popup windows....
    ::SetWindowPos(hWnd, HWND_TOP, 0, 0, 0, 0,
     SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE);
   }
  }
  break;
}

return m_pTreeCtrl->CTreeCtrl::OnNotify(wParam, lParam, pResult);
}
