I am sorry if I was a little harebrained but I was a little too excited when I wrote my last post.
For me the problem is resolved. I have a router failure. It gets too hot when several are logged on.
Now I have made myself a rule, in case it happens again.
Is the problem solved if you:
1, Restarting your browser. -------- Yes / No
2. Restart your computer ------ Yes / No
3. Restart your router. ---------- Yes / No.
4. Run virus scan --------------- Yes / No
5. If the problem is still there, you can ask for help.
