widget text is underlined everywhere
 

I am using Atahualpa 3.4.6. with wordpress 2.9.3. I have successfully added 3 text widgets in right sidebar. I am now adding 4th text widget, and the title and body content texts are all underlined everywhere. I added 5th text widget and same problem recurs. I did not tell it to underline. I have not changed any setting in styling widget panel in Atahualpa theme option panel. How can I remove the automatic underlining in the text widget?

Could you please post a link to your site?
