I have just digested this 3 years worth of thread. I only came across this because I have indeed came across the same issue. I have web clipped an article to the windows desk client and got some awful formatting with the double spacing that the shift-return didn't fix. I thought that I would be smart then copy it into notepad (the king of no formatting) and paste it back into a note and still there is weird double line formatting. This is just some weird shoyt. Keep up the fight. I will +1.
Please add me to the list of those effected. I just got the premium version and it's rather annoying.
