Just recently Safari became Yahoo search engine . I did nothing to cause this. I changed it to Google and then I noticed my Yahoo Mail was saying I had incorrect password and can't accept any mail. So I,tried Gmail and it loaded but does not bring up my mail either. The Apps do bring up mail. I have Deleted the account. Gone to Safari and deleted history, cookies Data. No luck. It's only since Yahoo started acting as my search engine in Safari. Any clues.?
