Desktop Client: IDEF0 lines disappear after drawing between shapes

This article applies to the iGrafx IDEF0 Client

When drawing an ICOM arrow between two shapes in an IDEF0 diagram, If the line seems to disappear after you name it, you may be able to correct the situation by drawing a line that does not connect to any shape, and then dragging the endpoints of this new line to the shapes. This may then workaround the problem, making it possible to simply draw the lines in the usual way for all subsequent lines.
