For the last few days, I have had intermittent problems posting comments in a thread. I click on comment, and nothing happens. Then I try reloading, and again, nothing happens, but by then, everything is expanded, which is a PITA. Often, even after I have reloaded, I am still unable to post.
As a separate, though possibly related matter, I have also found CH to be very slow to load. This is also intermittent, and not a problem I have with any other site. I have a new, 3 month old Mac, and Fios, so everything else is really fast.
