[Arch Linux] How to make mousepad produce line breaks, etc that windows can read

I have been using Arch Linux with just Xfce and mousepad as the text editor for nearly a year now.
But I have yet to figure out how to save text files with Windows line retus, etc at the end of the lines.

I know how to do it in Ubuntu just fine, but any time I save a text file on my USB drive and then copy it into Windows, it's just a single long line.
So, it takes a lot of work to get it like it was in Arch.

Does any one know how to get mousepad to do this?
Any help would be greatly appreciated.
Thanks in advance.
