WM_CTLCOLORSTATIC with NULL_BRUSH has trouble on Vista Aero

I created a transparent dialogbox. To make the static text control in the
dialgbox to be transparent, I processed the WM_CTLCOLORSTATIC with the code
like this:
case WM_CTLCOLORSTATIC:
{
HDC hdc=(HDC)wParam;
SetBkMode(hdc, TRANSPARENT);
}
return (INT_PTR)GetStockObject(NULL_BRUSH);
This worked very well on Win98, Win2000, WinXP and even on Windows Vista
without Aero.
But, if the Aero is turned on, strange thing happens.
The static control turns into a black block. It seems that NULL_BRUSH does
not work in its usual way.
Does anybody know how to fix this? I do not want to turn off the Aero by
force in my program.
Thanks a lot in advance.
