How did my post appear twice?

I only clicked "Post" once. Could the fault lie with my mouse?

There are two seconds between the time of the posts. Could have been a double click.

I have had a post not go through, checked for it in another window, waited over a minute and a half and clicked again, only to get two posts dated nearly two minutes apart. Sometimes the system is slow.
