Reasons for Return links

You may of course not implement return links and leave "'close' strict mode" in KSW Options unchecked. Then 'close' will be enabled for all topics (see Close Strict Mode Option). After closing the HI frame, one can return to the KB frameset just by pressing 'Back' in browser.

However, if you follow a link to a second topic, and then another to a third, you'll have to 'Back' all the way to get to the KB again.

Secondly, when users call a topic from Favorites, there is no link to open the HI frame.

And thirdly, Firefox 'Back' button returns to the KB frameset home, not current topic, which requires an extra step of re-selecting the current topic - that's when visitors use Firefox.

If you choose not to implement return links, you may consider adding a default/front page link to your topics' header, so that at least there is a way to navigate back to the KB when no other means are available.
