Hi,

Not sure if you've observer any similar behavior but a graph that was running fine before seems to crash whenever I enable the background preview and start navigating it. Here's a sample traceback from the crash:

Object reference not set to an instance of an object.

I don't have any DynaShape nodes currently placed on the graph and it's not a terribly heavy graph:

Any idea how I can avoid this without removing DynaShape?

Engine does not use 'TOTAL AREA' (index 8 in example CSV) or calculate from 'QUANTITY' and 'AREA' leading to incorrect bubble areas for analysis

BackgroundExecutionAction is still active when:

1. The Solver.Execute node has been deleted.
2. The Solver.Execute node has become inactive
   Potential fix: use tasks chaining rather than one single task with an indefinitely while loop
   So far we have only checked for the case where the current workplace is closed
