7feeds ticker not stable

I like the 7feeds ticker a lot and it suits my needs perfectly, but it’s not stable enough – it freezes occasionally, and the web browser prompts me to stop it’s execution. Although it doesn’t happen very often, I’m worried that it will draw visitors away from my site (http://www.freebiking.org). Please try to debug it and make a more stable release available.

BTW, does anyone know of a plugin that does the same (shows a RSS or Atom feed, capable of showing not only the title, but also the content, scrolls it inside the widget), but is more stable?
