I've used opera mail for years without any problems. Suddenly I got a lot of problems. It all started when I addressed a web site. Opera crashed. I restarted opera, and crash again. Did this many times, and could read a message that a file in opera mail was in use. Started taske manager and tried to stop the file, but got no access. Restarted opera again and was happy to see that it didn't crash. Then i noticed that opera mail was downloading hundreds of emails, which couldn't be right. Then tried to email myself a test mail. I received it, but opera mail continued to send that message over and over again. I have also installed opera mail on my tablet, and that test message continues to come several times every day.
I've thought of uninstalling opera and then reinstall, but are afraid of loosing all my emails and contacts.
Anyone has some good advice for me?
