Hangs as in never finishes and I don't know what, if anything, it has done.  But that suggests some tests for me to run that I should have thought of.  First, create a test .xls that does nothing and see if that runs to completion.  If it does, then create a test .xls that simply creates a file to test whether it actually creates the file.

Can you tell me how to do this?  When I run the ps command in a terminal session, I see this:
$ ps
      PID    PPID    PGID     WINPID   TTY     UID    STIME COMMAND
     5780    5568    5780       3408  pty0    1000   Nov  5 /usr/bin/bash
     5568       1    5568       5568  ?       1000   Nov  5 /usr/bin/mintty
     3716    5780    3716       1016  pty0    1000 18:58:16 /usr/bin/ps
     1820       1    1820       1820  ?       1000   Nov  5 /usr/bin/cygrunsrv
     1856    1820    1856       1892  ?       1000   Nov  5 /usr/sbin/cron

Do I have to kill the cygrunsrv and cron processes and then ??

Okay, I think what you are telling me is that the login I'm using on "my" WinXP PC (which I inherited) must be an administrator login and the login I'm using on the Win7 PC is not an administrator login (it isn't).  That sounds plausible (I know a lot more about UNIX than I do about Windows).  So the differences I'm seeing between WinXP and Win7 is due to using/not using an administrator login, not due to whether it is WinXP or Win7.
