Did you try using the scroll on the address list? it shows the first two and puts a scroll on the right of the list. (I think it is right. I don't do much in mail with multiple replies.)

When I tried to reply to everyone on a message thread, only the sender and the first two recipients popped up. There were about 12 people on the thread. I'm not sure how to fix this...I tried quitting Thunderbird and opening it again ;-) but that didn't help. Also, is there any way to make the type bigger in my inbox? I adjusted the preferences but that didn't help. I'm not talking about the text of the messages, but the subject lines and senders. Thank you for any insights!

Thanks much1 I just didn't think about using the scroll bar. i was expecting to see the addresses lined up like they are when I send the original...

Thunderbird does not line them up on one line to send them, some add-ons do that to mimic the way outlook express and outlook do it, but Thunderbird does not do that.

This add-on does the magic of changing the size of the user interface fonts and widgets.
