"More" buttons and profile settings

1. In the list of profiles, next to each profile is "Fields / Settings / More>". On my installation, the "More >" button isn't working (Firefox, Opera or IE). Likewise, in the list of fields for a particular profile the "More>" buttons against each field don't appear to be working either.

2. Separately, when you edit a field in a profile (e.g. to disable it) the displayed name of the field is resetting to the default for that field, rather than the display label it had been using. I don't remember it working like that in previous versions.

3. As a trivial point for information, in Opera a disabled profile is showing to me as red with strikethrough. In Firefox it just appears in red.
