netconf GUI problem

The server in my problem is the Linux Mandrake which functioned as the DNS server. Normally, I can modify the named.conf file by the forworder menu in this netconf GUI window.But I cannot do it anymore since last 2 days. The netconf window has immediately closed when I selected this menu and the error message "Segmentation fault (Core dumped)" displayed.
However I still can access some menu in it. The named process restarted and server restarted cannot solved this problem.
What should I do? Is it possible to reinstall only the netconf of Mandrake?

I think this just reinenforces the importance of not using a GUI on a nix server. BTW, I believe that netconf is an RPM and can be reinstalled. Though this may not solve your issue. Things dont generally break without a reason.

I would just edit the named.conf file directly, it just seems easier....
