I've just installed Thunderbird - which I have been using for years on my desktop and laptop - on my wife's laptop. No matter what I try, I cannot locate the inbox. I'm instructed to right-click on the account name in the folders panel, but the account name isn't there. I'm offered only Mail, Address Book, Tasks and Chat. Right-clicking on the Mail option offers Open In New Tab, Open In New Window and Switch To. I can write and send an email, choosing either of two accounts, but I can't seen incoming/received ones. I have a feeling that I'm going to be embarrassed by the answer, but I'm stumped.
