Flash security and local file playback
In Presio, when publishing to Flash - sometimes you are unable to view the player controls (play, pause, seek, the video itself) while previewing the presentation. The player area itself appears blank. In this brief screencast I describe the reasons for the issue, and show you how to fix it.

Beginning with Flash Player 8 Macromedia has changed the security model that’s applied to local Flash content. By default, Flash applications that are run from a user’s local file system rather than over HTTP have more limited privileges starting in Flash Player 8. By default, local Flash content - can no longer contact the Internet, perform HTTP communication, or communicate with local HTML files. The security measures are in place to ensure a system is secure even if it runs a malicious flash file directly on their machine - much like Microsoft has improved security around ActiveX controls.
So, what do these new security measures mean when publishing to Flash with Presio - well in certain cases, you may publish a presentation and the media player area (play, pause, seek bar, video itself) is blank.
Most of times this will not be an issue, because when you install Presio - directory is created that says trust Flash content created by the program Presio. Well, for a variety of reasons this may not always work. Windows permissions, publishing to shared drives, burning to CD/DVD, and other reasons may cause the special file to not be created properly.
