[Plugin: Copygram widget] Problems customizing widget

Hi!

Very nice widget! Exactly what I’ve been looking for! Very nice grid indeed. However, when I try to customize the widget nothing really changes. I want to have 6 images at 75×75 pixels and minimum padding and link to full size picture. When I set the parameters, I get padding 5, link to Copygram and 9 pictures (default). Why won’t it change?
