I have no drop down choices in iWeb. So, for instance, I go to the Link Inspector. According to HELP I should have a drop-down selection under "Link to". But it is un-highlighted. No options. Doesn't work. Do I need to register the program or something to bring these features into action? Similarly, if I click the "Format" option in the Link Inspector, I cannot enter anything in the boxes. And the 'Use for New Links on Page' button isn't working. What I am doing wrong here?
