That would be a viable solution if my Screen Options toggle worked, but it does nothing when I click it (the contextual help button does not work either).
Screen Options works on every admin page except the Widgets page. I can also drag and drop the sections on my Dashboard page, but I cannot drag and drop on the Widgets page.
The Widgets page is basically a dead zone where nothing is clickable (except the standard page items in the far left column). I see the exact same behavior in both Firefox 3.1 and in IE 7, both with and without plugins active.
When I click on the Widget Screen Options, the address bar shows:
The "#screen-options" portion of the URL does not show in the address bars of other pages with working screen options, so I think this a clue to the what is going wrong. WP is not processing the Screen Options URL like is should be.
