yes thank you - I did a similar thing with Wayfinder which worked - but it just felt 'wrong'!!
Just out of interest, since my last post, we reinstalled again, and it all worked. I really have no idea why as we'd already uninstalled and reinstalled before. This time we made sure we rewrote all the Chunks and templates....
Hmm - that's exactly what happened to me - which is a little worrying - it feels flaky.
