When I log on to a site that I visit, (not this one) when I have gone through the motions of sign up etc., the site suddenly cuts off, and places me back on the desktop. I receive no error message,absolutely nothing. I am just left to work out the problem for myself. This has only just happend in the last hour or so, and I am concerned. Anyone out there that can diagnose the problem and remedy please, I'd be terribly grateful. Thanks.
