xman cannot display manpage

[WU, ALEX (SBCSI)]

My system is win2k/cygwin 1.3.18.

I have searched the mailing list, but could not find an answer.

I have a problem with xman, xman can show the first mapage fine, 
but it cannot show the second manpage. It displayed error message:
  cannot create /tmp/xman001960: permission denied

I have c:/cygwin/tmp on my system
drwxrwxrwt+  18 admin    adminstr    28672 Jan 15 13:34 /tmp

BTW, the manpage of xman says xman refers to /etc/man.conf, but 
the config file is actually /etc/man.config on the system.

Thanks in advance,
-Alex
