For what it’s worth department.
Hit the post/enter button once. FR is slow and takes a little time to post.
Every time you hit the post button will result in a posting. Hit once and
wait for it to post. Take care.
The only time it’s given me any trouble is when I got a 500 error, then it posted twice. That was a few days ago.
You’re right of course, tonight it’s been really slow, I knew that so I just waited. Got a 500 error once, didn’t check, but I’d bet it double posted.
