I am hoping someone can tell me why when I click on a slide in film view my main slide page stays black?
I'm a Windows user, but I recall seeing this issue specifically with macOS. So be sure you are running an Intel Mac and make sure you update to the latest version of Adobe Captivate 2019. Check out the following post for more details...
Just uninstalling and reinstalling isn't the answer. You need to make sure you install the specific version of Captivate that is compatible with your OS. The normal download install file for Captivate doesn't necessarily give you that specific version.
Yeah, make sure you download the installation file from the blog post I mentioned and install it rather than any other versions. This is the version you want to run.
