Schematics losing connection to their Diagram Version

I have a number of schematic diagrams that seem to be losing their "connection to the map" - i.e. the identify tool (the plus signs have gone) and propagate between schematic and map tools stop working. 

Is there a cause behind why a Schematic Diagram may lose this connection to their Diagram Version?  Is there anyway of repairing it? - Looking at "right-clicks" and data source tabs there seems to be a limited amount you can do.

(PS we don't want to rebuild some of these as our users spent 3 days getting them to where they were! )

Any suggestions would be great.



PS Version 9.3.1. Not the nice new 10.x!
