As long as I've been writing you'd think I know how to do this...

I copied a text document into Word. And it looks like a text document. Now when I type in changes, the new text will go over much farther than the original test. And sometimes it creates breaks in sentences where I don't want them. It looks like this:

I have no idea what
I'm doing because I usually use Wordpad. I guess that might
be a mistake. But I know
now why I do.
My simple mind can't handle so many options! <bg>

My question is... how can I get the entire document to look uniform without the tedious line by line work?

Please help me!
