rn notes

Hello,
I start to use FCKeditor and I'm having a problem - the notes "rn" insert between everyline and having 2 empty lines between every text line. for example - this is the original text:

Metallica – Turn the page

E
On a long and lonesome highway east of Omaha
D
You can hear the engine moanin' out his one long one note song
A E
You can think about the woman or the girl you knew the night before
E5
But your thoughts will be wandering the way they always do
D5
When you're ridin' sixteen hours and there's nothin' much to do

A5 E5
And you don't feel much like ridin', you just wish the trip was




and this is what I got:

Thank in advance,
