I've never had an issue with the latter approach. My understanding is
that the message queue can hold messages for any number of otherwise
unrelated windows created by the calling thread. GetMessage with a
NULL hWnd parameter receives any of those, and DispatchMessage
dispatches to the window procedure associated with their respective
window class.

Going to check and let you know. It's been a while since I have done a
lot of win32 API programming.
