Simply press ‘Preview Project’ from the ‘Project’ tab to see the results of your project settings, pages and scripts.
During previewing of your content, a toolbox is shown (this does not show during playback on your players). This can be used to see what is actually happening during playback, and can also be used to return to the Editor once you have finished (by pressing ‘Close Preview Window’).
If anything doesn’t run as you expect, edit the appropriate part of your project to resolve it.
For example, if nothing plays check that the ‘On Startup’ setting in the Project Settings, Screens and Pages option and set to play a page or script that you have created.
If a page cuts short, or doesn’t seem to play at all, check that the page time on that page has been set correctly.
