Can't drag fields, and Display fields wraps fieldsets oddly.

In the Manage fields tab, the instructions tell me that:
"You can add a field to a group by dragging it below and to the right of the group." But I am unable to do so. Also, the order into which I drag my fields doesn't stay when I go to add content.

In the Display Fields tab:
The fieldset options for each of my created fields are forced to the bottom of the page, instead of inline with the Label and Format dropdowns.
