The problem is back and has been happening to me for a few days now. Very noticeable and annoying.
Posting "Quick Reply" takes a long time, if not forever. If I interrupt it and click "Go Advanced" and then submit the post, it usually works.
I do seem to recall this being an issue a few years back
, and if my memory serves, the culprit that was revealed to be causing it was some ad network (Vigilink, maybe?) that was inserting some unreachable URL into the submission process. Maybe one of their servers is being unresponsive during this time, or something? Or maybe it was a rotating ad...
If that's the case then, the problem would only exhibit itself in sub-forums where it's performing it's post molestation. IE: Not this one.
