I am not sure what the correct behavior should be, as we do not have a RTL Windows installation.
We have set the "necessary" CSS for the editor content area, e.g.: direction: rtl;
From that point on, it is the browser that needs to take over.
One possibility might be that the Windows itself should be RTL-enabled (e.g. use Hebrew or Arabic installation).
In any case, if something needs to be changed further, you are welcome to modify the

To install the new version you need to log-in to your Telerik Client.Net account and download the latest SP from there.
