the program you are using to write letters in. It might be Wordpad, Works or Word from Microsoft, and a host of other programs from other companies (like WordPerfect or OpenOffice).
The answer is totally dependent on the program you use.
I own the Microsoft Millenium version (2000), and I need help, because everytime I open a new document and press the "Enter" key, instead of going to the next line, the "Cursor" ends up half way down the page, leaving a massive gap between lines?
I know that I must have done something wrong, because I've been writing letter's for years, this problem only started recently.
I just want to get back to normalcy. I want to add that this letter I'm typing presently is exactly what I want my documents to look like.
Thanking you in advance
