So maybe this started with the new Chrome update, but my HTML5 publication is stuck infinitely at the loading screen. Works perfectly though for Edge, Firefox etc.
Is it me or is anyone else affected? I have seen users face similar but I am 99% sure this is not due to any local setting/security enforcement. Console logs reveal that the resources are not being loaded.
Are you trying to run this locally or through a web server?
For overall best results, using a web server is recommended.
For local testing, I have had the best results to date with Firefox.
It could be that Chrome "fixed" something for you in an update.
Open the development console and post a screen shot of the error that is there. The image you show usually happens when it can't find the appropriate files in the dr folder (which contains a compressed version of all the images and text in Captivate)....but a console log will tell us (command opt J) on mac
