I’m having trouble with the carousel in Firefox when I have a horizontal carousel with text underneath that is centered for each item. Just after you click to slide, the text shifts a few pixels to the left. The shift only occurs when the text takes up the entire width of the item, so that it wraps, or just before it wraps.

Doesn’t occur in Safari, and IE 6/7. IE7 does have a similar issue in that the brief moment before sliding, the text underneath loses any anti-aliasing (cleartype) until it stops again. Not sure if there is anyway around that one.
