Description of problem:
Trying to edit a wired connection. change it to static, and enter details, but
OK becomes disabled

Version-Release number of selected component (if applicable):
kernel-2.6.25-8.fc9.i686
NetworkManager-0.7.0-0.9.2.svn3590.fc9.i386
NetworkManager-glib-0.7.0-0.9.2.svn3590.fc9.i386
NetworkManager-gnome-0.7.0-0.9.2.svn3590.fc9.i386

How reproducible: order of data entry is important.

Steps to Reproduce:
1. right click network icon
2. edit connections|wired|auto ethernet|edit
3. ipv4 settings
4. method=manual
     - result> OK button becomes disabled
5. add|192.168.16.105|255.255.255.0|192.168.16.1
6. click OK {which is greyed out}

Actual results:
nothing happens. user cannot save the settings.

Expected results:
OK should be enabled as soon as a legit ip address is entered.

Additional info:
If you add the address first, then select method=manual, the OK becomes enabled.

If you adjust the connection name={} even to add and then delete a character, so
that the name stays the same - the OK becomes highlighted.

ps. no workarounds!
pps. nice pickup on fixing allowing a maximum manual MTU of 100 in the earlier
version = thought we might have been headed for cell relay !
