Duplicate and triplicate posts are often appearing on these pages. To replicate:

1) Post in a thread.
2) Edit your post - your edits should appear.
3) Refresh your page - It will ask you if you want to Cancel or Continue. Pick Continue.
4) Your post will duplicate.
5) Repeat step 3, your post will triplicate.

I am on Google Chrome 25.0.1364.99

Work-around to avoid duplicate postings: If you edit your post, do not refresh your page afterwards. If you refresh, it will ask you if you want to cancel or continue. If you continue, your post will dupe. Instead, leave the thread and then come back in.
