At certain times, when I click to expand a comment, the "Loading ... Please Wait" is permanent on the left hand side of the screen in the floating text box.
I mentioned this before in another post about a bug here but I'll make a separate bug report. It happens randomly but not intermittently, just for an hour here or there it will do it for all stories all the time. I think that it's a problem with the server that provides the rest of the comment and information on the return request in the AJAX. Might just be too many users, see the screen shot.

See the left hand side with the permanent loading statement and also the bottommost post is not fully loaded.
