Does the log file get produced (look in /var/log/setup.log and
/var/log/setup.log.full).  If either of them mentions your latest install
(the one that hung), please attach the relevant sections (gzipped).  If
not, what are the symptoms of the hang?  Does the "Cancel" button work?

This is obviously not reproducible by most people here, so you may have to
debug this yourself.  Can you reproduce the hang on the debugging snapshot
of setup (available at <http://cygwin.com/setup-snapshots/>)?  If so, you
might try attaching to the hung process with gdb and getting a backtrace
(of all threads): "info threads" to get their numbers, then "thread #"
(where "#" is the thread number, e.g., 1), then "where".  Then post the
output here...
