Hi Alexander- Thanks for getting back to me. I don't think I explained it very well. Here's a thread for the same issue with SublimeText: http://wpjim.com/how-to-remove-extra-blank-lines-t...
I think it's a problem with the WP editor, but it's an issue that occurs in most text editors (I'm even getting it with textedit). Let me know if you have a similar fix- thx!
