Bob,
Working on quite a bit of jQuery AJAX over the past week or so,
I've noticed similar side-effects. I have no idea if my issues are
related to yours, but 90% of my problems were solved by using the
callbacks instead of expecting that linear execution would be fine
with the few things I was trying to call. Since I've stopped trying to
do anything but AJAX calls where I do them (and started using other
callbacks for things like .animate and the like), I've had nothing but
clean loading pages. Again, I doubt the issues are related, but the
symptom is at least identical. ;)
