Diagram changes automatically

[Prateek]

Hi all,

We are working on a project wherein we have some 40-50 diagrams. In the diagrams we have connectors to which we have added information by right-clicking on the connector then selecting
Advanced-->'Information Items Conveyed' option.

Each one of us has a replica which we upload to a sharepoint site. Finally we merge all files. The problem that we are facing from past 1 week is that somehow the position of the information placed over the connectors is getting misplaced when we upload the files and download at any other location. In the original file(i.e file where the information is added and placed over connector) the information appears to be perfectly placed.

We tried locking the diagram and then uploading but that also does not not work.
Is there any setting that we have changed by mistake or something else?? What can be done regarding this??
