I just changed to the new editor - and you can't go back again.
Once I made the change, copying and pasting from Word, - even using the 'post from word' button - stripped all formatting from the Word text.
Heard back from support that this is supposed to happen.
This is a real reduction in functionally - I am very disappointed that there is no warning on the site. We pay for these features, I feel Auctiva should consider their customers, before effectively tricking them into irrevocable changes
