I am using the "Widget List Items" (first, second, and third level) on the "Widgets" Admin screen to try to remove the gray bars beside the widget list items. I am trying to set the value of "Left Border Width for Links" to "0" - - it simply will not persist the value I choose. I have been modifying the database directly (because of the escape character issues) so I have been able to make the necessary change in my case.

Just thought you would like to know.

Thanks that's a bug and I've seen where the error is, will change for 3.1
