EVALUATION Before 6826397, a focus message generated from Java (sm_inSynthesizeFocus == TRUE) comes to the top-level handler: awt_Component.h: 690 LRESULT res = ::SendMessage(targetHWnd, WM_SETFOCUS, (WPARAM)oppositeHWnd, 0); where targetHWnd is always the top-level window So, the proxy handler wasn't called for such focus messages. After 6826397, all focus message (including the messages generated from Java) always come to the proxy handler first: awt_Frame.h: 380 retValue = ProxyWindowProc(message, wParam, lParam, mr); So, the proxy handler is called now and in this particular case (EmbeddedFrameGrabTest.java), the proxy handler generates "unexpected" WM_ACTIVATE/WA_INACTIVE and it generates the ungrab request for the menu and the test fails. We can use the sm_inSynthesizeFocus variable to see if the focus message comes from Java (or not) and call the proxy handler (or not call).
