I have built a few custom themes with the JQuery UI theme roller but on highlight the text in the buttons that is supposed to be white always turns black. This happens with my custom themes as well as the example themes they have on the site with similar layout. Is this something conflicting with the script? If so how could it be changed? The odd thing is that if you navigate to the submit answer page the "submit" and "cancel" buttons behave correctly.

I am also wondering how to change the light blue gradient in many of the fields of the script as they do not seem to be affected by the UI.
