Try this. It works for me:
- Make two layouts: landscape an portrait. Both with the same event sheet.
- Add the object "Browser"
- Add to the event sheet the following conditions (Browser) and actions (System - go to layout):
- Browser > Is Portrait --- System > go to portrait
- Browser > Is Landscape ---- System > go to landscape
Ah, why didn't I think of that? Great idea, thanks a lot!
