I dunno exactly what the Network tool is doing.

Not quite, the problem is, that network-admin expects plain ifupdown and so edit
/etc/resolv.conf directly. If you are using resolvconf and/or NetworkManager
this changes will be lost.

I agree, the situation is a bit unfortunate.
So, basically you have (legacy) net-admin which edit /e/n/i and /etc/resolv.conf
and on the other hand you have NM, which has read only support for /e/n/i, and
rw support for system settings via the keyfile plugin
(/etc/NetworkManager/system-connections).

Please wait until 0.7.0-1 hits the archive (currently in NEW) and read the
README.Debian about the managed/unmanaged mode.

If there is still something unclear, I can *try* to explain.

Run "killall nm-system-settings".
