Hey there, I've just upgraded to Leopard and I have some strange Mail problems. - When I click the dock icon Mail opens, but nothing happens. I have to manually open a Mail window in the taskbar. - All my mails are gone, when I go to my library folder I still see them, but they're not in Mail. - I use GMail, when I send myself a message from gmail.com I don't receive it in Mail. - Import and rebuild are greyed-out. - Quitting Mail doesn't do anything, I have to force quit. Macbook Pro 2.33 C2D OS X 10.5.6
It seems I've already solved the issue, deleted the com.apple.mail.plist file in Library -> Preferences. Everything works fine now..
