I did my testing with windows 7 and IE 8. A fresh install. IE did do the down load of Java C:\Program Files\Oracle\JInitiator 18.104.22.168. IE hung up. I removed the third party check and that did now work. I replaced the JVM.dll file. Then Added aisweb2 to the trusted sites and allowed pop-ups. That allowed things to run and sign in.
I was also able to sign in with Fire Fox
