Why are some menu items and buttons on the tool bar sometimes disabled?
Reactis has two primary modes of operation. The current mode of operation depends on whether Simulator is enabled or disabled. Certain buttons are disabled in each of the modes. When Simulator is off, the buttons that control a simulation (play, fast forward, reverse step, …) are not active. When Simulator is enabled, any buttons (and some menu items) related to modifying the .rsi file are disabled. In particular, all buttons related to editing Validator objectives are disabled.
