I give up. What's the trick to getting jCarousel to work with Safari/Chrome. Anyone figured it out yet?

Everything works great in FF/IE. When I pull up jCarousel in Safari or Chrome a 2nd time, the images display funny, or not at all. Shift+Refresh fixed the problem.

Any thoughts? anyone have the same problem and find a work around?
