Again, sorry about that. In the future I will try clicking once and then closing the thread then trying to reopen it later, with my crap internet service (Clear).
I have the same problem. When a train goes by, the internet connection seems to go haywire. After a ~reasonable~ amount of time, I just click the stop icon on the url, open a new tab, and go back to the thread to see if my comment has posted. Nine times out of ten it will have posted, if it hasn’t, you can go back to the previous tab and try to post it again. This way you don’t lose any pithy comments :)
