Convert Captivate 9 Blank Project to Responsive

Have you tested the HTML5 output to determine if you really require a responsive project?

If you have a working draft, just publish with only the 'HTML5' button checked.

No, I'm sorry. A theme (object styles, master slides) for a responsive project is too different. You can use the assets from the Library in the normal (blank) project to start with for the primary breakpoint view but you need to use a responsive theme. To use those assets, open the original Library as an external library (File menu).

Nope, no way but to re-create as responsive.

But if a project is blank, why the big deal about starting over?
