I love Thunderbird - in fact I have just switched over to it from Outlook (mainly because I can run it from memory stick and use it on any computer I happen to be using at the time).
My only niggle at the moment is that I don't seem to be able to persuade it to select the inbox as the default folder on startup which is frustrating to say the least. At the moment every time I run the program I end up looking at the junk folder. ](*,)
Is there any way to achieve this?
