Double Posting after I preview post.

Hello,
I have noticed that I'm double posting a lot, and it appears to happen only after I preview my post first.

I make sure that I click ''post'' button only once, but quite often my post still comes up twice.

I am using Google Chrome, if that is a relevant factor.

EDIT TO ADD: I experimented by previewing this post before I posted it, and this thread has also been double posted.

It appears to happen after I alter some text after previewing.
