I'm not an expert in the animation sytem -- you should open a ticket
(dev.jquery.com) and get some others to take a look at it.
When I stepped through the code, I found a potential problem here, line 3043
of jquery.js
// We need to compute starting value
if ( unit != "px" ) {
self.style[ name ] = (end || 1) + unit;
start = ((end || 1) / e.cur(true)) * start;
self.style[ name ] = start + unit;
}
The div in question has a starting position of: left:-50%;
The value of "end" is 50, unit is "%".
All of the other divs that had a positive percentage were handled correctly.
While processing this div the starting position was somehow altered to -4%,
leaving the ending position at 46% (-4 + 50).
I'm not that familiar with the animation plumbing, so I'm not sure why this
is occurring.

Hi Jeffrey, thanks.
I deleted the "float: left;", i didn't know was useless with
position:absolute;
Anyway, I noted the strange behaviour of the <li> elements too.
I uploaded jQuery unpacked... if you still want to have a look... ;-)
BTW, there could be something wrong with animate('left','+=50%'); but
that would mean a bug... :-|
Thanks,
Andrea
