Note: there’s a possibility that the editor may crash while trying to reproduce the issue. Sometimes the editor will throw UnityEngine.GUIUtility:ProcessEvent error instead of an exception or crash, the behavior is intermittent. This case was originally reported as crash, however, it wasn’t reproduced during testing.
