I should elaborate - it's the small GUI app that hangs, and in fact it 
hangs immediately after I COPY from within it - NOT when I paste into 
another window.

Just for fun I added a signal handler on QClipboard to respond to 
dataChanged(), and then I call OleFlushClipboard(), hoping that having 
the clipboard "render" the data manually would help. My app still hangs, 
but now I can safely copy into another window.

So I just need to figure out what is causing my app to hang after 
copying data. Obviously it has something to do with how I'm launching it 
from that other non-Qt app, because standalone Qt apps don't have this 
problem.
