It looks like the {\shptxt ... } is being set outside the {\*\shpinst.... } destination. From what I can tell, it should be inside the \shpinst destination.
No Text Box Appears in another RTF reader:
{\shp
{\*\shpinst\shpleft1394\shptop1949\shpright2999\shpbottom3385\shpbxpage\shpbypage\shpwr2\shpwrk3\shpfblwtxt0\wpshpflg1\wpframeparam2
{\sp {\sn dxTextLeft } {\sv 0 } }
{\sp {\sn dyTextTop } {\sv 0 } }
{\sp {\sn dxTextRight } {\sv 0 } }
{\sp {\sn dxTextBottom } {\sv 0 } }
{\sp {\sn fLine } {\sv 0 } }
{\sp {\sn shapeType } {\sv 1 } }
}
{\shptxt \plain\f0\fs24 B\par }
}
If I move the {\shptxt \plain\f0\fs24 B\par } up one level, then I can see the TextBox.
{\shp
{\*\shpinst\shpleft1394\shptop1949\shpright2999\shpbottom3385\shpbxpage\shpbypage\shpwr2\shpwrk3\shpfblwtxt0\wpshpflg1\wpframeparam2
{\sp {\sn dxTextLeft } {\sv 0 } }
{\sp {\sn dyTextTop } {\sv 0 } }
{\sp {\sn dxTextRight } {\sv 0 } }
{\sp {\sn dxTextBottom } {\sv 0 } }
{\sp {\sn fLine } {\sv 0 } }
{\sp {\sn shapeType } {\sv 1 } }
{\shptxt \plain\f0\fs24 B\par }
}
}
Thank you for your assitance,
