Hi Ralf,

We found a solution for your problem.
Actually, the erratic diagram is "Sequence diagram: Test 4 - Read On-Request Data, Part 5 - Read Product Name".

Please following these steps:
- Close all diagrams
- Open the erratic diagram
- Click on the background of the diagram
- Run the attached script. At this step, the ghost objects should be removed. In the script output zone, a message indicating that ghosts have been deleted should appear.
- Save your project

This is some explaination:
At a moment a Message has been deleted but some ghost executionoccurencespecifications stayed in the diagram. When you were trying to do modifications in the model, the diagram was trying to refresh but due to these ghosts it blocked any model modifications.

In Modelio 3.8, this will be fixed.

Let me know if it helps.
