Can you share the model?

IF leaving the program and reopening it causes the issue to disappear it could just be an error somewhere when loading the back end logic of the software. What happens if you reopen the file (after the error is gone) save the file and reopen it again? Does that remove the error permanently?

If not, as @Arun said, we'd need to see the file in order to debug it.

rob.fsm finally i have an example of the error (flexsim 2017.0.1). To get the error, run the model briefly...stop and reset. This model doe not serve a practical purpose but is the only one where i can generate the error systematically!

Your activities are structured such that they cause an infinite code loop.

It throws an exception to keep the program from crashing on your infinite loop.

If you put a Delay activity anywhere in that code with a value > 0, then it won't be an infinite loop anymore.

Errors when dragging objects into the 3D view are a common symptom of graphics issues.

Please see this article regarding graphics issues and how to solve them.

The short answer is to update your graphics drivers, but please check the article for more details and other ideas.
