To save me retyping a CV I had sent via e-mail I brought up one I had sent before from my sent folder to forward it to the new recipient.
Just out of curiosity I sent it to myself first to check the layout was OK.
When I opened it, the layout was not as I had initially typed it, it seemed to be scattered on to new lines where I think I had inserted full stops?
I had a similar problem with a document I was trying to email. Chuck kindly recommended I save it in Rich Text format which will not alter the format and is compatible with most software (sometimes other formats can't be opened depending on what the recipients uses).
