Clearing cache didn't work (Firefox 3.0.5). Decided to close it down completely.
And it now works, with links opening into a new browser tab!
Thank you so much for your support.
We're new to creating websites ... only 2 paying clients so far (our mainstream activity is copywriting and marketing). Twin Peaks is a freebee for some friends. We hope to have some more paying sites over the next few months ... and we'll use N13 for future News listings - and make a donation each time.
