I created a custom interface property called 'Trunk', this property will have a yes value if it is a member of
a trunk. When editing the interfaces that are trunks with 'yes', there are some interface full names that I need
to drag the bar to the right so I can see what interface it actually belongs to. The problem is that for some reason
it wont let me drag the 'Fullname" value to the right, but every other property I can drag to the right if I need to make it
longer. Any ideas on why this might be happening? I'm using NPM 2011.1.0.
