BUG: PeekMessage does not retrieve WM_PAINT messages

MORE INFORMATION

Steps to Reproduce Behavior

Compile the following sample code as a WinCE Windows Application. When the application is run, the application's window will paint correctly when maximized from a minimized state since a WM_PAINT message is sent to the window.

However, if the user clicks on the Start button twice, first to open the Start menu then to dismiss the menu, the application's window will not paint the area covered by the Start menu. This is due to the WM_PAINT message being posted to the window.

Sample Code:

    // PeekMsgTest.cpp
    #include <windows.h>

    #define WINDOW_TITLE L"PeekMessage Test"
    #define CLASS_NAME L"SampleWndClass"
    #define MESSAGE L"Click on the window to close"

    HINSTANCE hAppInstance = NULL;

    LRESULT CALLBACK WndProc (HWND hWnd, UINT uMsg,
                              WPARAM wParam, LPARAM lParam)
    {
        switch (uMsg)
        {
            case WM_PAINT:
            {
                PAINTSTRUCT   ps = {0};
                RECT rc = {10, 10, 200, 100};

                OutputDebugString (L"WndProc (WM_PAINT)\r\n");
                BeginPaint (hWnd, &ps);
                DrawText (ps.hdc, MESSAGE, lstrlen (MESSAGE),
                          &rc, DT_LEFT);
                EndPaint (hWnd, &ps);
                return 0;
            }

            case WM_LBUTTONUP:
                DestroyWindow (hWnd);
                return 0;

            case WM_DESTROY:
                PostQuitMessage (0);
                return 0;
        }
        return DefWindowProc (hWnd, uMsg, wParam, lParam);
    }

    int WINAPI WinMain (HINSTANCE hInst, HINSTANCE, LPWSTR, int)
    {
        WNDCLASS wc = {0};
        MSG msg = {0};
        HWND hWnd = NULL;

        hAppInstance = hInst;

        wc.lpfnWndProc = WndProc;
        wc.hInstance = hAppInstance;
        wc.hIcon = NULL;
        wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
        wc.lpszClassName = CLASS_NAME;
        if (RegisterClass (&wc) == NULL) return -1;

        hWnd = CreateWindow (CLASS_NAME, WINDOW_TITLE,
                             WS_VISIBLE,
                             CW_USEDEFAULT, CW_USEDEFAULT,
                             CW_USEDEFAULT, CW_USEDEFAULT,
                             NULL, NULL, hAppInstance, NULL);
        if (hWnd == NULL) return -1;

        ShowWindow (hWnd, SW_SHOW);
        UpdateWindow (hWnd);

        while (1)
        {
            if (PeekMessage (&msg, NULL, 0, 0, PM_REMOVE))
            {
                if (msg.message == WM_QUIT)
                    break;
                DispatchMessage (&msg);
            }
        }
        return 0;
