Thanks for replying both of you. Factor-fiction you are a lifesaver! Did not realise a 7 year old great grandchild was so clever!
I looked on the Bing Explorer bar and clicked 'history' and it showed as 'Turned Off'!
I turned it back on and then unticked 'delete history on closing' (or something like that) in internet options - then I went into my sites and re-entered all passwords (message came up each time at bottom of screen to say yes/no)
Now back to normal so thanks so much
