Comment 3 for bug 1005531

Workaround for this bug:

Click on the port text-box. From now on you don't see what you are doing any more since the + and - buttons are consuming all space. But the text-box is still there, you just can't see it. So you blindly do:

* press Control-A to select all text in the box
* backspace to delete everything
* type the new number
* hit enter
* verify the number
