    If I have used the IMessenger API, Messenger wont exit (shows that pesky
    "There are other applications currently using features" dialog).

    I have boiled it down to the following console sample, which only calls
    CoCreateInstance() and Release().

    AFAIK everything is released and cleaned up, but the application must be
    closed before messenger will exit.

    What am I missing?

    #include <windows.h>
    #include <objbase.h>
    #include <stdio.h>
    #include <conio.h>

    const GUID IID_IMessenger =
       {0xd50c3186,0x0f89,0x48f8,{0xb2,0x04,0x36,0x04,0x62,0x9d,0xee,0x10}};

    const GUID CLSID_Messenger =
       {0xb69003b3,0xc55e,0x4b48,{0x83,0x6c,0xbc,0x59,0x46,0xfc,0x3b,0x28}};

    int main(int argc, char* argv[])
    {
     HRESULT hr;
     IUnknown* pMsgr;

     CoInitialize(0);
     hr = CoCreateInstance(CLSID_Messenger, NULL, CLSCTX_ALL, IID_IMessenger,
    (void**)&pMsgr);
     printf("CreateInstance=%u=0x%X\n", hr, hr);
     if (pMsgr)
     {
       pMsgr->Release();
     }
     CoUninitialize();

     printf("Try to exit messenger now.\n");
     _getch();

     return 0;
    }
