Multi-Line editable text field

I am setting up a standardized GUI for our products and I am running into a major problem with editable text fields. I need to set up an e-mail form on a GUI page. The name and subject fields are fine but I can't seem to find a way of creating a field where the user can put a carriage return in their text. This will probably be localized eventually so I am trying to avoid any bitmap text solutions.

Any Ideas, suggestions or solutions?
