When I am on the widget interface it does not respond to any clicks.
I have a 3 column theme but it only shows widgets under "Sidebar 1". I try to click on "Sidebar 1" and "Sidebar 2" to collapse but nothing happens. I try to drag widgets from and to the "active" and "inactive" sections to both sidebar sections - nothing. I even tried to click on "Screen options" and "Help" but nothing happens.
All other sections sections of WP 2.8 seems to work fine. It is only this section that is not responding.
