Sidebar 2 widget edits can’t be saved–Missing “Save Changes” button

The title pretty much says it:

I’m trying to modify the Page widget, which is in Sidebar 2. Now I make the modification I want, but there is no “Save Changes” button.

How did I get them in there in the first place? You might ask… It was created in an earlier version, and on upgrade, (which I expected would be the case) the widgets were there, where I had put them, etc.)

I tried it in Firefox, Opera, Sea Monkey, and the “Save Changes” button doesn’t appear under the widgets, which I what the system says I should press to save, before I leave the page.
