I don't mean inside a post, but on the frontpage, when you view comments instead of posts. Sometimes when I switch from 'view all comments sorted by new' to 'view subscribed comments sorted by new' (or vice versa) I get it to show up for a second or so, before it disappears. Usually I just get an endless spinning bear head.
I'm guessing y'all are aware of this, but I could not find a post on it, so I thought I'd mention it at least. Peace
