Attempting to preview multiple posts always fails

Currently editing multiple posts at the same time in the same session will cause the "Duplicate submission protection" message to appear.

This message isn't exactly accurate, and can occur for a multitude of reasons... it's quite annoying really even for us. We're definitely looking into alternate ways to fix all the issues caused by this "protection".

In the meantime, I'd suggest only having one edit screen open at a time when doing some hardcore forum posting.

Thanks!
