If you are worried about users clicking through the course too fast for the browser, try making the navigation buttons not initially visable and then add an on show action at the title level for each button set to show the button. This way the navigation buttons will not be displayed until the page is fully loaded. You can even add a delay to the action for an additional couple of seconds.If you are worried about users clicking through the course too fast for the browser, try making the navigation buttons not initially visable and then add an on show action at the title level for each button set to show the button.
