Description: Sorry for the triple post, but I've managed to reliably reproduce the error. If I:

1) Moderate a post, and then after the page reloads

2) click "mod/reply" on a comment, and then

3) hit "back" without modding or replying to that comment, I get the Confirm Form Resubmission message.

I don't get it if I do steps 2 and 3 on the same page but in a different tab.

Also, if I hit "back" after moderating a post (not a comment), the post reloads. I have to hit "back" a second time to get to the main page. I've had the Confirm Form Resubmission message pop up a couple times over the last few days, but tonight is the first time I've noticed the unusual page back behavior.
