Hello, I am trying to Create an empty window, which process the WM_MOUSEMOVE message in WinProc:

case WM_MOUSEMOVE:
    {
        HWND otherHwnd = HWND(0x000608FC);
        POINT pt = {LOWORD(lParam), HIWORD(lParam)};

        ClientToScreen(otherHwnd, &pt);
        PostMessage(otherHwnd, WM_TIMER, WPARAM(4096), 0);
        PostMessage(otherHwnd, message, wParam, lParam);
        SendMessage(otherHwnd, WM_NCHITTEST, NULL, (LPARAM)MAKELONG(pt.x, pt.y));
        SendMessage(otherHwnd, WM_NCHITTEST, NULL, (LPARAM)MAKELONG(pt.x, pt.y));
        SendMessage(otherHwnd, WM_NCHITTEST, NULL, (LPARAM)MAKELONG(pt.x, pt.y));
        SendMessage(otherHwnd, WM_SETCURSOR, WPARAM(otherHwnd), (LPARAM)MAKELONG(HTCLIENT, WM_MOUSEMOVE));
        break;
    }

I hope I can hover the hyberlink in IE, but result is the hyberlink only be showed as hover style in a very short time, then it turn to normal, and then again hover, then normal. At www.amazon.com, when I simulate to hover the link("Today's Deals ") , the link is blinking.

I think there is a better way to do it, even the IE window is covered with some other windows, it can make the IE act with the mouseevent. waiting for the best solution~ orz

Above is the spy++ logs when I realy hover the link. and the simulate is as same as the real message
