In Chrome 8.0.552.224 on Windows 7, I found a bug in which I receive what looks to me like the raw, unformatted output of an ajax call vs having that output incorporated in the page correctly. I seem to be able to reproduce it at will in Chrome. I was going to say that Firefox 3.6.13 didn't have the same problem, but I banged on it some more and recreated it there too.

Here's what my page looks like when I follow the steps below:

Here are the steps to reproduce in Chrome:

• Load serverfault.com
• click on my username at the top to load my profile
• scroll down to "Answers" section
• click on any of the "answers" page numbers to to go any page but #1 (so, click "2" or "next")
• click on any of the answers to load that question page in the same tab
• click the back button to return from the question page to the profile page
• scroll back down to the "answers" page numbers again
• click a different page number
• Boom, all the data that should be loaded in the answers section, but in a new page, not incorporated in the profile page.

Steps to reproduce in firefox (this works in Chrome too and is actually a simpler way to reproduce, but I'm leaving the Chrome steps because it's how I found the problem organically which might be useful reference):

• load serverfault.com
• click my username to load profile page
• scroll to answers
• click one of the numbers to go to a different page of answers (2, for instance)
• F5 to reload the page
• scroll back down and click another answers page index number (2 again will work)
• And again, what appears to be the ajax response rather than the page w/ the response incorporated into it.
