I am using OE 6 under XP SP2.

I have just tried using the Contact List to send emails instead of using
Tools/Address Book. Should have done that years ago.

One peculiarity puzzles me. No matter which contact I select, the text
portion of the message gets double spaced. (If I use my old method of
creating mail via Tools/Address Book, the text is single spaced.) I found I
could fix that for individual contacts one at a time by changing the format
from HTML to Plain text. Is there a way to make all contacts Plain Text all
a once without doing it for each one?

Is it normal for the text to be HTML when using the Contact List?

Thank you.
