I've installed the sidebar widget in wordpress mu and am using a theme that is sidebar widget enabled/accepted. In the configuration of the widget (under presentation tab --> Sidebar Widgets) I've noticed that I'm able to drag and drop the widgets I want to use. However, when I click on the configure icon (located on the widget), it does nothing. It should open up a 'pop-up' window that allows widget configuration. I feel like I have this partially installed. Any suggestions?
