1) Script Title: Horizontal Accordion script

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...haccordion.htm

3) Describe problem:
I use the script with wordpress on various pages. Switching from one to another makes the script stop working. The only way I can get it back to function is clearing the cookies (several times).
Its seems to happen when I switch from a page with many slides to a page with fewer slides. I have no experience with cookies, do you have any suggestions how to fix this?
