Selecting Animation - Continuous Play will set play commands in the Continuous mode.
In continuous play, when the last frame is reached, the Current Density Viewer will start over at the first frame and continue to display frames until a stop command is received. If the play direction is reverse, when the first frame is reached, the Current Density Viewer will start over at the last frame and continue to display frames until a stop command is received. If Continuous Play is off, then when the last frame is reached, in forward play, or the first frame is reached, in reverse play, then the Current Density Viewer stops changing frames in the display.
