You want to hide the right-click menu under Windows (Ctrl-click on the Macintosh).
You can't disable the Flash Player's pop-up menu entirely, but you can minimize the options shown in the menu by setting the Stage.showMenu property to false.
By default, the following options appear in the Flash Player's pop-up menu when the user right-clicks in Windows (or Ctrl-clicks on the Macintosh):
You can remove most of the menu options with the following line of ActionScript code, although the Settings and About options remain in place:
Stage.showMenu = false;
Unfortunately, Flash does not provide a way to disable the menu entirely. Furthermore, Windows users are accustomed to using right-click to display a pop-up browser menu that allows them to open a link in a new window, for example. Such options are not available due to the Flash pop-up menu's presence. It is possible to use a third-party utility such as SWFKit or SWF Studio to completely disable the menu for enhanced Standalone Projectors (Windows versions only), as shown in Recipe 2.10.
See Recipe 2.8 for a way to display Flash's Settings dialog box without requiring the user to right-click (in Windows) or Ctrl-click (on Macintosh).
