[jQuery] Problems getting position of an element inside blockui

[jQuery] Problems getting position of an element inside blockui


Hi, I'm having a problem understanding how to get the right position
of an element inside a blockui div.
I'm using blockui of Mike Alsup, and dimensions plugin.
Here you can view an example page:
http://lab.gianiaz.com/jquery/helptip-blockui/
In this page I use the jquery hover effect to show near a link an
helptip with some text inside it.
Every time the mouse pointer pass over an element with a class
".helptip" I get the position of the element and I move the helptipbox
div near the overed element.
It works well, but when this is applied to an element inside a div
shown with blockui the position taken with $('').position.top() and $
('').position.left() are wrong.
Can you help me?
Thank you
