I'm working with Captivate 9 and yes I've already found contributions to it, but I don't understand some of them.
I'm working on a very big project and it's so that I create most of the graphics in Power Point because it's better and easier.
I did some tests a few days ago to see what is possible with Captivate and noticed that Copy & Paste of PP objects works. These are inserted as clipart objects into Captivate. This still worked a few days ago and since then I have changed some settings and now all of a sudden it doesn't work anymore. I don't know why but it really worked! There are a lot of people who say this wouldn't work but I wonder why it worked for me and no I didn't imagine that. I have some objects that were taken over exactly like that O_o therefore I ask myself what is now going on that does not work any more.
Maybe you ignore that a ppt file (and a cp file) is a zipped folder. Change the extension to zip and you can unzip the folder. That will allow you to extract assets from the PPT which you can import in a Captivate Library and use wherever you want on Captivate slides.
