Some links work on flash page and others are inactive/disabled
I'm using latest version of flash player. My son does homeschooling via K12 online school system. The online application flash player application has links throughout. There are links that are active - as you scroll over you can see the mouse pointer change. And there are links that when you scroll over them don't change mouse pointer - inactive or disabled? I've searched all over and can't seem to find how to get these links to work. Much of the homeschooling curriculum is dependent on these links as you can imagine. I've disabled Norton firewall/anti-virus and no success. Flash player seems to be working properly. I'm on Windows Vista using IE8 using flash player 10. I have Norton 360 V3. Flash player seems to work fine with most other apps, it's just these certain links in k12 online curriculum system that seem to be inactive/disabled. We need to get around this, and not fall behind in the schooling, so any help would be tremendously appreciated. Thanks.
