Slideshow won't work when gallery is password protected.

Lani

As it says in the title, the slideshow option in my galleries works fine usually, but when I password protect them, for some reason it locks up when viewed on other computers, it works ok on mine.. Remove the password, and it works again.I would really appreciate some help on this as I have clients wanting to view their images.
The gallery is as below:

Password is Cassidy

Kind regards, Lani.
