Sorry, I haven't seen anything like that. However, the other day in the symposium when I visited a thread all of the post were cascading inside of each other (like when you quote quotes, etc.). It was like that with all threads in that forum and wouldn't go away even if I refreshed. Eventually, though, when I revisited it didn't do it anymore. Is it just here? And if so then does refreshing the page do anything, etc.?
