Tooltips that are working fine in BDS2006 are not showing in C++Builder2007.

Below are relevant code snippets:-


HWND hWndTipAlpha;
TOOLINFO tiAlpha;

//---------------------------------------------------------------------------
__fastcall TwMaintRegNewMod::TwMaintRegNewMod(TComponent* Owner) : 
TForm(Owner)
{
 AssignBalloonTip(hWndTipAlpha, tiAlpha, eAlphaCode, "Invalid Character",
          "You can only type an alphabetic character here",
          TTI_ERROR, TTF_ABSOLUTE | TTF_IDISHWND | TTF_SUBCLASS | TTF_TRACK 
| TTF_TRANSPARENT,
          (TColor)clCream, (TColor)clBlack);

}
//---------------------------------------------------------------------------


The code below is in a KeyPress event:-


       if (hWndTipAlpha)
       {
        // Set the position of the Editbox tooltip
        // If the form moves, the co-ordinates are still valid
        TPoint pSrcCo, pTipCo;
        pSrcCo = Point((eAlphaCode->Left + (eAlphaCode->Width/2)),
                (eAlphaCode->Top + eAlphaCode->Height));
        pTipCo = ClientToScreen(pSrcCo);
        SendMessage(hWndTipAlpha, TTM_TRACKPOSITION, 0,
              (LPARAM)MAKELONG(pTipCo.x, pTipCo.y));
        SetWindowPos(hWndTipAlpha, HWND_TOPMOST, 0, 0, 0, 0,
               SWP_NOACTIVATE | SWP_NOSIZE | SWP_NOMOVE);

        SendMessage(hWndTipAlpha,(UINT)TTM_TRACKACTIVATE, TRUE,
              (LPARAM)(LPTOOLINFO)&tiAlpha);
        SetWindowPos(hWndTipAlpha, HWND_TOPMOST, 0, 0, 0, 0,
               SWP_NOSIZE | SWP_NOMOVE);
        eAlphaCode->SetFocus();
       }


Are any code changes required ?

Help appreciated.
