I have a couple of paragraphs in which I use scrolling text with perspective
as a special effect. It will sometimes get jerky and not run smoothly
through all of the text. Is there anything I can do to stop this? I have
tried shortening the text, but with no luck.

Is this a common problem or is there possibly a problem with my system? I
run a 900MHZ AMD Duron w/768MB RAM, and a 32MB NVidia graphics card.
