Problems with HTML5 on new MacOS update

Hi there,

Updated to MacOS Mojave 10.14

Using Captivate 2017 release

Chrome and Safari browser

Previously on High Sierra, no issues with publishing.

Now when I publish or preview my file in HTML5, the screen shows a spinning wheel, and the HTML5 never starts.

I read on one forum of one way to overcome this i.e. by turning off playback bar on the skin editor before publishing. Tried it, and it works.

But this is obviously a temporary fix. I still need my playback bar so are there any permanent fixes to this problem?

Thanks
