The problem was that copying something in Notepad caused the clipboard 
integration manager to take ownership of both the PRIMARY and CLIPBOARD 
selections in X.  Selecting text in an xterm took ownership of the 
PRIMARY selection away from the clipboard manager.  Unselecting the text 
in xterm released ownership of the PRIMARY selection, but left the 
CLIPBOARD selection supposedly owned by the clipboard integration 
manager (which means it thought it had text to copy from Win32 to X, but 
it didn't).

I changed the behavior slightly to release ownership of the Win32 
clipboard and mark both X selections as unowned if one of the selections 
in X is released and the other is owned by the clipboard integration 
manager.  In fact, I should take this one further and release ownership 
of any selection owned by the clipboard integration manager when 
something is selected in X.  The current fix will probably work in 90% 
of cases for the time being.

I'd really appreciate some feedback on the new fix in 
XFree86-xserv-4.3.0-63, which should be hitting mirrors within a few hours.
