I'm having a weird issue when scrolling a font. I did the smooth scrolling tutorial on kirupa

http://www.tutorialized.com/tutorial...Scrollbar/7844

I noticed that before I learned to embed characters, the scrolling worked great! However, when I embedded the characters in the properties menu–the text looked much better and smoother, but the scrolling became jaggedy. Am I missing something? How can I achieve a smooth looking text with a smooth scroll?
