The Output > Zoom > Replay Delay command allows the user to specify a time delay between perimeters when redrawing a zoom window. This creates a animation of the simulation progression.
Selecting the Output > Zoom > Replay Delay command brings up the "Replay Delay" dialog box. Enter the time delay (in milliseconds) in the spin box and click the OK button. Then create a zoom window using the Output > Zoom > Zoom command to redraw, or redraw an existing zoom window by right clicking in the zoom window.
