Works Ok for me.Using W/8 and IE8.Maybe check to make sure your flash program is enabled on add-ons. No idea if that could be the cause or not but I don't have java installed and have script disabled in developers tools.
I suppose it could be a problem if greyed out, If script was disabled on mine i would not be able to use my broadband speed program and other things that may require it. Have you downloaded the latest updates from Microsoft last night. Or do you have script turned off elsewhere. Have you tried clicking on it and wait about 10 seconds for it to run or is it just greyed out and there is nothing that you can do with it. I probably would not worry about it unless it affects any programs that you try to download or run. It may sort itself out.
