Mary said she was having problems replying to her e-mail: she cannot (in her reply) quote the message she received, and it is possible that the cursor does not appear in the message window when she is creating a message.
Her Internet Service Provider is People PC.
We were not able to get as much information from her as we would have liked…IF she is using a People PC e-mail account, she can try to use the People PC webmail interface.
(There are many more time consuming things I can think to look at…)
