Topic: AIR Problems // Loading Screen Frozen // Live Preview Obscures Content

Harman, the current developers of AIR, have recently removed support for WebKit (the embedded browser which JuiceboxBuilder uses for the live gallery preview on the Customize panel) from the AIR runtime package.

If you are using AIR v33.1.1.821 onwards, then you may see the JuiceboxBuilder loading screen appear to be frozen.

If you are using AIR v33.1.1.932 onwards, then you may see the live gallery preview obscure other content within JuiceboxBuilder.

The solution is to use the most recent version of AIR with WebKit support.
At the time of writing, this is currently AIR v33.1.1.744.
Harman have made this available at the foot of their AIR runtime download page: https://airsdk.harman.com/runtime

Please uninstall any other versions of AIR first before installing the most recent version or AIR with WebKit support.

Apologies for any inconvenience caused.

Update:

According to this comment (over in the Harman Github Issues pages), it looks like Harman are currently looking to replace WebKit with a new embedded browser:

We've been looking at enabling third-party html rendering engines to be hooked into AIR so that the earlier behaviour could be restored...

If/when Harman implements this, there will no longer be a need to use AIR v33.1.1.744.
Although there is no problem in using AIR v33.1.1.744 (JuiceboxBuilder actually requires only AIR v2.0 or later to function fully), it would mean that anyone could just grab the latest AIR runtime without running into any problems.
