hi thanks for that ,but it seems to be a problem with iCloud on the mac as i signed out from safari on iCloud then deleted history from my iPhone then signed back in and relaunched safari and the history was gone and never appeared again so fingers crossed its fixed now ,but just as a test i build up a new history on safari then tried to delete it but it reappeared after a few seconds so i don't know it thats normal or perhaps a bug ,many thanks
