Not sure if this adds more detail:
I don't think I've modified your "Scoring Box" button from your theme (I've changed the widget and subwidget contents, but not the button behaviour, I don't think).
I've been able to reproduce:
Open the theme First thing i do is go to Controls, and select the Scoring Box button.
I get the ATVO - Error:
"Object reference not set to an instance of an object"
and the related log file is pasted below.
As mentioned, I've duplicated lots of widgets and subwidgets, and so there are lots of instances of the same objects with the "Copy of .." prefix to the names.
I wasn't able/willing to rename some because after much experimentation I learned that some of the scripts are hard-coded to the widget names and I was breaking too many things .. so i've left lots of names that don't really reflect what they relate to, and have multiple copies of the objects as a result.
That probably has nothing to do with it . but thought I'd mention it :)
