Greetings!

The application I'm working with is a VC++ app that has a Web Browser
control. After a certain sequence of operations, the web browser
control displays a web page that contains the control I'm working on.
The control works fine. If I run the application in VC++'s Debug mode,
I am getting an assertion failure when I exit the problem. The failure
occurs on line 365 of wincore.cpp. Here's the method that's failing:

LRESULT CALLBACK
AfxWndProc(HWND hWnd, UINT nMsg, WPARAM wParam, LPARAM lParam)
{
    // special message which identifies the window as using AfxWndProc
    if (nMsg == WM_QUERYAFXWNDPROC)
        return 1;

    // all other messages route through message map
    CWnd* pWnd = CWnd::FromHandlePermanent(hWnd);
    ASSERT(pWnd != NULL); // <=== FAILURE HAPPENS HERE
    ASSERT(pWnd->m_hWnd == hWnd);
    return AfxCallWndProc(pWnd, hWnd, nMsg, wParam, lParam);
}

// always indirectly accessed via AfxGetAfxWndProc
WNDPROC AFXAPI AfxGetAfxWndProc()
{
#ifdef _AFXDLL
    return AfxGetModuleState()->m_pfnAfxWndProc;
#else
    return &AfxWndProc;
#endif
}

nMsg at this point is 2, and wparam and lparam are both 0.

Since my application leaks memory after this, I'd like to clean it up.

Thanks very much!
