Greeking of text below 7pt on JPEG previews

Hope somebody can help us with this...

We use the InDesign CS2 Server to create and export InDesign documents as JPG preview files, but any text below 7pt appears greek. If we do the same in the indesgn CS2 client, the text does not greek.

We are running Windows 2003 Standard server and InDesign CS2 Server version 4.0.2.625

Is there any seting in InDesign CS2 Server to not greek text on exported JPG Images below 7pt?

Thanks in advance.
