I think I fiddled (how unusual!) and whereas I could
delete e-mails and they would remain until I emptied them
from the Delete Items box, they now don't go there ...
there is no second chance. I have scoured the options and
settings; I have looked through everything I can dream
of; and I can't see what I have done or what I can change
to fix it. I have done what 'help' says and get nowhere.
Any ideas please?
