I lose messages from my email IN BOX occasionally. I think it is when I have a message open that has links that I am traversing. When I return to the IN BOX, I find that the message has been lost
That sounds strange.
I have just sent a couple of test messages containing links to my ntlworld address but I could not reproduce what you are experiencing.
It would be useful to know the "View" and "Sort by" settings that you are using in webmail, (see images below). Post back with what you have ticked in those two drop downs.
If nothing else I could then try again using exactly the same settings as you and see if that throws any light on what is happening.
