As I said, I'm new to Captivate -- just a few hours'
experience with this particular tool.
My company is starting to create e-learning courses and one
of the trainers created a 3-slide template for us to use. The first
slide was a splash screen and the next two were created from
PowerPoint slides using the company's template. He imported these
three slides into Captivate and made a template there. That was the
template I downloaded into Captivate.
Then when I created additional slides using PowerPoint and
tried to import them between his slides #2 and 3, the slide content
only appeared in the thumbnails.
When I clicked on that "ppt.png" line in the Thumbnail view,
I noticed that the entire slide was selected. That's what gave me
the idea that the PowerPoint template had somehow been imported as
a graphic. Even when I imported slides with no template, the same
thing happened if they were placed after slide #2. (What can I say
-- beginner's luck, I guess.)
