How do I make the links to outside websites work in my ebook when reading on ADE?

I'm reading an epub ebook on my ADE.  There are links to websites that I want to go to, but I can't make the links work.  I click on them, but nothing happens.  I know the links are active because I've used them before in other readers.

Help!  Do I have to turn on links somewhere?  And if so, where?

Do links work at all in ADE?

Thanks in advance for the help.
