My latest trouble with Leopard which is really testing my nerves to the limits. I clicked on the mail app icon to open it as usual to be faced with a dialogue box "Welcome to mail" and setup up new account. I have done nothing differently at all. The last thing i installed on the computer was the latest apple software update this morning. I checked the mail folder in user>library>applications>mail and folders for my mail accounts and old messages are there. I have no idea what happened and certainly don't like the idea of having to setup all my accounts again (I have about 10 different mail accounts). Has anyone faced a similar problem? any idea why this has happened?
