I'm using Fm9 on xp, I have to control the Stretch value in Properties Font in every instance, in particular I have to retain changes I made with FM, up to now when I open my xml file changes are lost. I suppose I have to declare this attribute in r/w rules but I don't know the sintax. Can someone help me? Or where can I find a complete reference for r/w rules? I have the Structured Application Devepoper Reference and Guide but is too lacking. thank you.
