<div>message loop which will not exit until a Win32 call to</div>
<div>PostQuitMessage. But MFC also starts a message loop, and it requires</div>
<div>its own PostQuitMessage to exit properly...</div>
<div> </div>
<div>Since only one PostQuitMessage gets issued when you close the MFC</div>
<div>dialog, only one of the message loops gets exited. The other one</div>
<div>persists waiting for a future PostQuitMessage.</div>
<div> </div>
<div>Simply not calling Start avoids the problem. Start should only be used</div>
<div>if you are NOT using MFC, Qt, or some other GUI framework that already</div>
<div>does a message loop for you...</div>
