Run: Depressing the Run button puts the simulator in Run mode. Electric and magnetic fields turn on. Model views and microscopic views become available. Conductors and insulators take on their "active" appearances. On insulators, magenta hashing replaces the gray hashing seen in Stop mode. Conductors become shiny.

Users cannot access the Standard Menu. Other than this single exception, users have the same ability to interact with the simulator in Run mode as they do in Stop mode.
