In demonstration mode XTrkCad is driven by a script file (such as created by the Record command). The cursor is simulated on the Main Canvas and the XTrkCad windows (except the Demo window) are inactive.
The Demo dialog is displayed which contains a number of control buttons and a text area that shows comments on the demonstration being run.
A number of options and controls (such as Scale) are changed while running demonstrations. These will be restored when the demonstration is finished.
