Thanks guys!
This did it for me. I'd never got HTML reports running using v2, despite following all of Steve's instruction and suggestions - until now.
Ckeditor has been a bit flaky - working for some installations but not others, despite seemingly identical installations, but once I got ckeditor working, inspired by the last post, htmlreports only started working when I put g2 last in the module list - which I'd never have thought of!
All now working - except the schema browser widget at the moment won't work with g2. So I can create and edit with g2 disabled, and run live with g2. Good enough for now, at least to play around!
Thanks again.
