Program Not Visible upon Startup

I’m running OS X El Capitan Version 10.11.2. I’ve downloaded the latest version of Storyboard Pro with the appropriate license. The program successfully opened once, but on repeated openings it minimizes and “disappears” when I create a new project or try to open an old project. It behaves as if the project is successfully opened, and I’m prompted to save my work upon closing. Any help?

Hi Bradford – this has happened to me occasionally, and here is what has worked for me:
Press the number 3 key to go back to Drawing View. If this does not bring the screen back, jump up to the top menu and click on Windows > Restore Default Workspace

I hope that helps…
