Thank you for your reply, but I already tried all that and it had no effect. I tried resettin everything to default, closed TB, reopened it and put in the setting I want. No success.

Plain text messages will display in Times when I'm composing them, but are received in Ariel only. Plus when I open a plain text message that I've previously sent, it's turned into Ariel!

On the upside, HTML messages are behaving as they should. I guess I should be grateful for that.

Apologies for the typos - one of the cats walked across the keyboard just as I clicked on Post Reply. Somehow they always manage to step on the Backspace and/or Delete keys, haha.

Brilliant, thank you!! The "Fonts for" setting was probably the only one I didn't play with and it turns out to be the solution. I'm absolutely delighted. You're a genius and you've made me VERY happy this morning!

While I have your attention, I'm a little curious about the Text Encoding settings at the bottom of the Fonts & Encodings box. Outgoing is set to Unicode (UTF-8) and Incoming is set to Western (ISO 8859-1). Can you tell me (in simple terms) why they are different for Incoming and Outgoing? I'm not having a problem, just trying to learn something.

Thanks again, all for now!
