Hi Joseph,
Pierre is correct that there were some rendering issues with the first patch levels of SAP Screen Personas 3.0 when rendering in SAP GUI for Windows (and hence with SAP BC).
Please make sure you have the latest patch level for: NWBC, SAP GUI, and above all for SAP Screen Personas.
(The latest I have found is SP02, but please check on the SAP GUI forum.
SAP Screen Personas 3.0 SP2 now available. New analytics, theming, social, and admin features.
Best wishes,
Julie R Plummer.
