CefSharp.browserprocess doesn't remember "Don't show again"

The checkbox to stop the CefSharp.BrowserProcess overlay doesn't work. I am met with the overlay every time I open either LaunchBox or LaunchBox.Next (which I love by the way) eventhough I check the box to say "Don't show again for this version."

I am using the Free Version and don't know if this is a limitation of it.
