Richard,

Apparently, bash doesn't react to the shutdown message that Windows XP
sends it.  I've observed similar behavior with Windows 9x.  Can you close
the bash window via the 'X' ("Close") button?  If not, then it's possible
that the correct WM_CLOSE message simply isn't passed to or handled by the
bash shell (and any other console Cygwin process).  On Windows NT/2k,
using the 'X' button sends a HUP signal to the shell.  This doesn't seem
to happen on Windows 9x (and, possibly, Windows XP -- I don't have an XP
system to test this on).  You could try to incite someone knowledgeable in
Windows messaging (not me, sorry) to investigate this further.
