Recently, Oracle Learning Library (OLL) has undergone some UI changes. I believe this is an effort to make it usable also on tablets but I might be wrong with that.

In addition you will find a new TOI on installing Siebel 18.104.22.168 and higher with Oracle's very own Universal Installer.
You can find the the new Siebel TOIs here. All you need to enjoy them is a free oracle.com account.
