Right, got an issue with SWP - and that's because there's some HTML/JSON text in the response that looks like an UpdatePanel, but isn't..yet. See TFS 3152, the text is in a script just below this paragraph - I've copied it exactly as
it is in the broken page, so at least we'll pick it up in the same way.
It causes Console errors because ASPx doesn't exist - but it still appears in the source and will still bork the Update Panel code.
Note that if this script is outside of an update panel itself, it doesn't cause any problems. It's only when it's included as part of the update panel content that is creates an issue.
