This affects the port dialog too. Empty should equate to the default (7777), but the Confirm button is disabled until something is typed into the field.

There's a method in the text input popup class (forget the exact name) that marks the input as invalid when it's empty. Should be an easy fix if someone would like to make a PR.

I was looking into it the other day out of curiosity. I'll be unavailable for about a week, but if there's no rush I can take another look when I return.
