I agree with Danni. Make sure you have the latest drivers for your video card. This can either be found at the manufacture site for the computer (being Dell or HP, etc) or if it is a self built computer, find the type of card (Nvidia, Radeon, etc) site and locate the type of video card you have. To find out what type of video card you have, if you dont know, go to Start -> Run -> type in: dxdiag This brings up the direct x diagnostic tool which if you go to the Display 1 Tab, you will find you information about your graphics card. It should list the manufacturer and model. From there visit http://www.java.com/en/download/inc/windows_upgrade_ie.jsp this is the latest version of java you can download. Once you have both these things done you should be all set. If you have any questions or could provide more information, we can formulate other ideas if the above doesnt work.
