Maybe you have switched from composing in plain text to composing in HTML? In HTML the message text only goes to a new line when you give an enter. Otherwise it wraps at the tight side of the window. It will probably display the same way on the receiver's computer, depending on the width of his screen. You can try to see if this causes your problem, by holding the Shift key before clicking the Compose button, to start composing in the alternate way (e.g. in plain text instead of HTML). If you prefer plain text, you can change the configuration under Tools -> Account Settings -> [account] -> Composition & Addressing and toggle the preference Compose messages in HTML format. Note that this is a setting per account, and for news accounts it defaults to plain text...

I tried it and it didn't change anything that I can see. I also am missing a toolbar (I think) that allowed me to move click on print size at the top of an outgoing message.

I am not very computer savvy so I find this frustrating.

Thanks for your help.
