After opening the new PandoraBot control, I selected the config button. I made no changes to the config and closed it using the "X". The following error message appeared:
EZ-Builder forced a shutdown of the application.
I reopened, then added a PandoraBot control again, but I "Paused" the control. I opened up the config and closed again, this time no crash.
So, it appears that opening the config while the control is running causes an application crash.
