Since plusnet introduced the new look webmail I've been experiencing a problem - when I click to view a message I don't get that message, I get a different one (different sender and subject). Is anyone else having this problem?
I haven't seen that particular problem, but the "advanced" webmail does mess about with the display of the emails you click on.
Go back to the "basic" option - the one I prefer - and see whether you still have the problem.
