Unable to add Dashboard widgets
Not sure when this broke, but it is not possible to add dashboard widgets on 2.0-BETA1 right now. You can click the "+" to add a widget, then pick it from the list, but all it does is produce a spinner and if you click Save then refresh, the widget isn't there.
You can rearrange (Maybe- See #250) and save positions of existing widgets and close widgets, but not add new ones.
Tried in Firefox 3.5.6 and Opera 10.10.
