Slide effect bugs in IE 6 and 7 since version 1.1.3


Hi all,
I have issues with the slide effect since the version 1.1.3 (same
issue with 1.1.4):
_ Flicker effet when the div is sliding up, just before disappearing.
(working fine with 1.1.2)
_ The slide effect don't apply to a div with a relative position when
the doctype is strict
Everything is working fine with firefox, but with internet explorer
it's a different story.
It there sonething wrong in my code or is it a bug?
