Well, (NEW Problem alert ?!?) ...
For the first time since, it seems, end of MAY, I managed to get
into the new, transferred Email, (though during Login DID get the
screen where it says you're still BEING transferred)...
Used it briefly in "Basic HTML" mode, then turned Java ON for the
regular email, and deleted over 900 messages recieved since May ...
Sent a test message ... all worked

...so logged out...
Now, the Logout link...
htps://identity.virginmedia.com/vm_sso/idp/logout.action?referrer=google.com
... seemed to "lock" 3/4 way through,
and never went to the "You are logged out" or whatever next
page. Soooo, I tried to login IN again ... but THIS time the system
seemed to detect a "slow connection" and would only let me in
using the "Basic HTML" view.
As I'm the ONLY one using this computer, I looked for a "Stay
Logged-In" option as Yahoo Mail has, but couldn't see one,
so wonder is it POSSIBLE to stay logged-in ...(permanently)... ?!?
so as, once IN using Mail with the "Standard", (Java ON) version,
I don't need to go through a handful of Login screens/Refreshed Pages
each time ? ? ?
