Drag & Drop of widgets doesn't seem to work anymore. I've tried both Firefox 3.6.15 (my primary browser) and IE7, so I'm confident it is not a browser issue.
If I put my pointer over a widget (anywhere), I get the crosshairs, but then can't drag/move them. For now, I must "Enable Accessibility Mode" on the Widgets page and Add/Remove/Hide widgets manually. Not a huge deal, but certainly less convenient.
Is this a "bug" or was the feature removed for compatibility reasons?
(I'm using v3.1, but I only recently noticed this "problem", so it may go back several WP versions.)
