K Tooltip

Hi all first of all my english is not the best, so sorry for that! I bought this little, cool K Tooltip-Template. http://activeden.net/item/k-tooltip-as3/52285

so, I tried add this tooltip to a scrollbar (mc) in my movie and this works fine. The Problem I have is, I have 5 Pages with text (dynamically loaded from an XML file) If I start the movie F12 in Flash for the first time, then I go to one fo the page’s with the text, and rollOver the scrollbar (mc) the tooltip works fine. When I go back (main menu in the movie) and again to the text-page, the tooltip appears all over the movie instead of scrollbar.?? You can try it here: www.b-and-s.ch/test (The page is ugly, I know, so please no comment to this:)

In the description file is written something about (setting boundary) like: KTooltip.boundary = new Rectangle(0, 0, 1024, 768); /* set the boundary so tooltip is always inside this rectangle */

but If I do that I get an error: 1119: Access of possibly undefined property boundary through a reference with static type Class. Warning: 3594: exec is not a recognized method of the dynamic class RegExp. (I think there ist an error in the .as file)

anyway, setting the boundary doesen’t solve my problem, I think?!. Can anybody help me? many thanks in advance for every help regards marco
