Thanks for building this theme. I am not sure if this is a bug or if I did something wrong. I seem to be having difficulty getting the fieldset formatting to work. I noticed that there are two things happening:
1) On the edit content areas, all of the expandable pieces are not able to be expanded, and there is not an image for the arrow be able to open and close the fieldsets. I have temporarily changed this function over to the Garland in order to be able to use it. This happens both in FireFox and IE6.
2) On the user editing page, using the admin, when I open up a person's username and click edit, there are a whole bunch of fieldsets that are crunched up to the top of the page, overlaying other areas. Specifically, the theme configuration information is overlaying other information. This happens in both FireFox and IE6, and I also believe Safari.
I have attached a couple of screenshots. Perhaps it will be something that you have seen before.
