Theme information in style.css being corrupted

I use Notepad2 to edit style.css

I opened it in Notepad++, and there were extra line breaks on every line.

I opened it in Dreamweaver CS6, selected Commands > Apply Source Formatting, and all extra line breaks were removed.

I uploaded it, and it now views normally in the browser (Originally viewing style.css showed the line breaks were gone).

The Theme information is now displaying properly.

Note: the style sheet was displaying properly in Notepad2 originally. Perhaps Notepad2 handles line breaks differently.

Thanks for your help.
