After clicking the link to the inline edit demo page, the page loads with an alert. Clicking the alert goes to an error page, saying the page cannot be displayed.
Steps to reproduce:
1) Open the inline edit demo from the daily build site:
2) Notice that an alert message pops up. Click 'Okay'
3) Notice that you are now taken to a page that says that the page cannot be displayed.
Oddly, in IE7 you can hit the 'back' button, and the page works.
