HtmlEditorExtender - can't insert links

hi

I am using HtmlEditorExtender but I have some problems, when I want to add links to my text.

I select some text and click the "Create link"-icon.
It looks fine, but when I save the text and show it Again the text I linked to has got an underscore in front of the linktext, and there is no link.

I save the text in a database. The field consist of this text: 
here is the link _test</A>

As you can see - no link.

I need help to solve my problem. 

Thanks
