First I would like to say that I am really digging the look and philosophy of Composite C1 :)
Now on to my issue/question...
Yesterday I used Webmatrix to install C1 on my local machine. That went fine, no problems. I fired it up (as an aside, please please get it working in Google Chrome. Really is the best browser, IMHO) with no problems and looked around at various features
in various perspectives. All good so far.
I decided I would take a look at the editing functionality so I chose the About Us page in The Composite C1 Demo Company website and clicked Edit Page.
The tab for that page does appear with the four tabs (Settings, Content, Metadata and Preview), however the rest of the content never loads. All I get is the Windows Spinning Icon of Doom. To do anything else, I have to close the tab and reload. Bah.
I also Added a Page and the same effect occurs.
I have tried this in both Firefox (latest) and IE8.
I am really looking forward to seeing if this will suit my needs.
P.S. I am following your efforts on Stack Exchange as well and I am rooting for you all! :)
