Description

Sometimes closing the Analytic View can cause Constellation to completely freeze up and become unresponsive. This occurs when there are at least 2 graphs open and the Conversation View open. This also happens when the Conversation View is replaced with the Layers View.

Steps to Reproduce

1. Open or create 2 graphs

2. Open the Conversation View and the Analytic View

3. Close the Analytic View

4. Observe that Constellation is unresponsive

5. Also occurs when the Conversation View is replaced with the Layers View.

Expected behaviour: Constellation to continue being responsive

Actual behaviour: Constellation is unresponsive

Reproduces how often: 100%

Additional Information

Both views can be empty for this to occur. Graphs do not need to have conversation data and the Analytic View does not need to run an analytic.
