The message "Stay on Page" or Leave Page" comes up when I have typed a message and have not sent it or saved it. Then I say stay on page, my original page comes up, and I can either send it or delete it.
I was having serious troubles a month or so ago. I finally called Frontier. They said I live in a high use area. I was told to upgrade at $10 more per month. What a difference. I think that is a lot to pay for something others get for nothing, but it sure was worth it to relieve my frustration over what had been happening on my computer.
