I'm opening an xpage in the Notes client, in which server-side javascript generates several paragraphs of HTML content including some links (anchor tags) to external sites. How do I make these links open in a new tab or window?

All the links open in the same tab if they don't have a target attribute.

If I add target="_blank" to each anchor tag, which should open them in a separate tab, the links don't work at all. Clicking them produces a brief colour change in the link text, showing that the click has been registered, but the linked page never opens.

The links with target="_blank" work when the xpage is opened in an external browser. They only fail in the Notes client.
