Hia,
I think you mis-interpreted my post. I am fully able to get to the configuration screen of the webpart (I am an experienced SP user!!).
The problem lies (and for another user I think) is that on my configuration screen none of the edit buttons appear for some reason.
When I get to the 'choose list' and 'choose display fields' options, all I have is a text box …. no drop down selection of site lists. This initially suggested I had to type the url in manually but this didn't work.
When I eventually found your help files and saw your config screen I realised I was missing the edit buttons which enables auto selection of lists and fields etc…… no tick boxes for me 😉
I'll try and re-install it on my test server, maybe something went wrong when it when it got deployed. It's not urgent for now, just something that I can see massively improves the rubbish forum offering out of the box lol
