I have a Sony Vaio laptop (using Windows 7) which has recently developed an odd fault. When I click on a specific email in order to delete it, the email below it will also be deleted at the same time. Also, when clicking on an email to open it, it will often keep opening it without actually displaying it on the screen, rather it just minimises them at the bottom. I have searched through the computer settings to see if I might have accidentally changed something to cause these problems but have found nothing. Can you help me sort this out, as it is time-consuming and frustrating to deal with! Thanks.
