We need help over coming this configuration, and Config the Server to use LTR Format configorations when open in IE.

We couldn't find any formal note which describes how can we control it from the server side.

We are using Design Studio 1.2 SP02 Over BO4.1 SP02.

Does anyone have an idea?

thanks
