Desktop Client: If your diagram is not displaying text inside the shape boundary (within the edges of a shape), it can be because of one of the following reasons:

There is not a default printer defined on your machine. Please ensure that a default printer is defined in Windows. This can be important for proper functioning of several iGrafx features; you should ensure a default printer is defined.

You are using a shape that does not have text layout boundaries set to be within the shape.

You are using a shape that does not have the 'Grow to Fit Text' option set (on the General page of the shape Properties), and text is spilling outside of the shape boundary lines.
