I just submitted an answer here, it came up with the CAPTCHA check, then I clicked the submit button once. Two same answers appeared 30 seconds apart in time. I've never had this happen before so thought it worth mentioning.

I've deleted one of the duplicate posts so only high rep will see them both


My browser history shows the following sequential actions during the process of submission - I have left nothing out.
The first entry is me doing my ahem "research" on Wikipedia

and the last is me visiting meta to post this question.

I'm using Chrome 5.0.375.70

There have been times where I posted an answer and meant to edit the post but hit the back button instead. Click post the second time and, boom, two duplicate answers.

I can't say this is what happened to you but I would have sworn up-and-down that I did not hit the back button but my browser history said differently.
