pasting article into blog

For some reason the window or whatever it is for pasting an article into my blog does not like to have articles pasted into it. I'm sure there is a technique, but I have noticed job offerings on odesk commenting on the problem. My other blog is on wordpress and their program really makes a mess of it. I gave up trying to post articles in the Ghostblogger site.    Why these people don't understand that people use word processor programs escapes me. At least tell us how to do it. (I found out how. Use notepad)
