Invalid viewstate errors

Hi Joe, we are seeing increasing numbers of "invalid viewstate" errors recently, e.g. when saving (losing) edits to a blog post we had this error below, but also on other events. Any thoughts on what might be causing this? v2.4.0.9 on full trust.

Re: Invalid viewstate errors

have you added any js to the skin recently that might be doing stuff that affects the hidden fields used by viewstate?

other than that I have no idea
