Twice in the last 3 or 4 days I have clicked the submit button and received a message along the lines of:

"This post is a duplicate of a post that you made in the last five minutes.........etc"

Now, I know that I haven't posted for 24 hours before the latest message and I didn't double click.

I realise that it might be the mouse, but have not experienced problems with anything else.

Anyone else seen this?
