Sorry, wasn't very clear. The line that was failing was:
var caption = link.up().previous();
whereas if it's changed to
var caption = $(link.parentNode.previousSibling);
it always works (exactly same data sets).
I have a sneaky suspicion it may be that when it's failing it's
because IE doesn't consider link to be a Prototype Element, just a
vanilla HTMLElement. Why, I don't know, as it never happens in FF or
Safari.
