If the tabs are not working, or not showing up on your computer, please follow the steps below.
Look at the top of website page. If there is a bar with a tan background saying something like "this website wants to run active content, do you want to allow this". Right click this and say allow blocked content. Refresh the page if the tan bar is not there
If a pop-up alert came up when you open up the site, saying something like "this site run active content, would you like to allow this", refresh your page and allow the content. There should be an allow or don't allow button on the pop-up.
If you still cannot get the tabs to work, try reinstalling, or downloading Adobe Flash Player. Click here to go to the download site.
