I believe that I initially used Opera (which is my preferred web browser) to access this site, but now at the top is displayed some add about Kidz bop or something and it takes forever to move anywhere in the site. Do I have to use explorer or do I need to adjust something to use opera?

Also even with IE I have a lot of trouble with the slider on this site. Is this just my computer or is it the site?

Thank you in advance for your help with any of this.
