The new informational page for DVD Architect 5.2 lists,
"DVD scripting - DVD Architect Pro software supports the ability to create and run scripts in final DVD or Blu-ray Disc design. With scripting, you can build robust interactivity into your projects."
I attempted to utilize scripting in a Blu-Ray disc project and it failed to link properly. When I downloaded the DVD Architect 5.2 manual, it states that scripting is not available for Blu-Ray projects. This is the same as it was in version 5.0.
I'm assuming the feature is not missing, but that the text above on the website is incorrect.
