Text editors

I had a student who suddenly couldn't use the html editor anymore when she had been able to use it a few minutes before. I suggested to her to check ZoneAlarm if she had it but apparently instead it was Norton Firewall that was causing the problem. We don't know why it suddenly changed its settings but she was able to come up with a solution based somewhat on Bryan's instructions. Just thought I would share this if anyone else has a student having this problem.
