Contact Widget Plugin disables Widgets admin

Hi Everyone,

I'm bringing up my first Multisite and I'm having an issue with the first plugin I'm trying to use. When I activate the Contact Widget plugin it disables/prevents the JavaScript features on the Widget admin page. Basically, you can't do anything on the page except navigate away from it. I've turned off all other plugins to avoid conflicts. Same issue. When you deactivate the widget, the Widget admin page works again.

Any ideas?

Cheers!
David
