So here I am in IE 7,
So here I am in IE 7, reporting out the details. 3.6.12 is the latest (stable) version of Firefox, and I've updated all of my add-ons. Wait, actually, one wasn't up-to-date, so now I've updated to the latest version of the ActiveGS plugin...and after restarting Firefox, I can type in the comment fields again!
A little copy and paste and this is actually coming in via Firefox...go figure.
