All we have now is Visio 2013, don't have the old version.
And with copying shapes from another document, I get the error even when copying shapes from one of the old visios to another. I can copy from drawing to drawing within the same document without a problem, but trying to add a shape from outside the document, regardless of source, seems to be causing the issue. I think my descriptions might be getting a bit confusing, so let me re-explain it all so hopefully it makes a little more sense, and include a little more info to maybe help out.
-My company has these long-maintained .vsd's that contain flowcharts for complex calculations.
-The primary shapes used in the documents are: Predefined Process, Card, Direct Data.
-Got these names from the Shape Name tool.
-Each document contains a large number of pages, each with their own unique drawing.
-I can copy a shape from one page to another page without issue. When a new page needed to be added, this was how it was created, copy paste the shapes needed rather than create new ones.
-When we copy a shape from another document, the shape pastes into the document fine, but when we try to copy the text inside the shape, we get the referenced error.
-This occurs with shapes made in a new visio document as well as trying to copy shapes from one of the older documents into another of the older documents.
-We found this issue when we used a tool to auto-generate shapes for new calculations, which would have saved time, and tried to put them into the new document.
