right hand margins are too wide on email messages

I use free AOL email and recently when composing a message on email the text goes beyond the right margin than normal, in other words the text does not stop at right margin of the email box, I think they call this wrapping but I am not sure.

I use Windows XP Professional with SP3. I checked my PC resolution and it is on the highest (I have never changed it to a lower rsolution), checked the AOL email settings and all is fine there (there is no option to adjust the margins of the text on the email boxes but I believe they are set the right way with normal left and right margins).

I don't know how or why this is happening i came up all of a sudden when I turned on my pc and tried to send some emails to friends that's when I realized something was wrong. I googled the issue but found very few entries related to Yahoo mail where app[arently you can clikc on mail options and adjust the margins but not on AOL.

I would appreciate suggestions on how to fix this big inconvenience and to prevent it from happening again.

 

I just noticed that this happens nwhen I write the text directly on the mail box BUT NOT when I write the text elsewhere and then copy and paste it on the mail box (then it won't go beyond the right margin). This is strange!
