You may encounter an issue whereby links within a diagram, are not aligned with their respective objects, for example a drill down arrow may appear in the center of the page, but the arrow is un-clickable.
Issue/Introduction
Issues with link alignment in the web server
Resolution
If there are hidden metric links and they fall outside the bounds of the rest of the diagram then they can affect the scaling of the diagram. This issue has been resolved in v10.2.0 HF5. You should upgrade to this version for permanent resolution.
As a workaround, the following can be done:
Enable display of all metric attachments on the diagram.
Delete the metrics that are not currently displayed.
Change the diagram layout so that all metrics (even the hidden ones) fall within the bounds of the other diagram objects.
