YAY, Foustie, you fixed it!!! I had been having this exact same problem on my work computer (for weeks now) and I just went to the settings, found that interface thing, and changed it to the full fledged option and voila! The reply box is once again enabled! I wonder if it is the same problem cello is also having. We will have to let her know to check those settings as well. So glad you figured it out!
