Clearing out the old files in the ~/Library solved the problem. Thank you !

An old gallery I made works fine if I open the index.html file in Safari so I know that components (config.xml, for example) are okay.

I have updated Adobe Air to Version 22 and JuiceBoxPro to 1.5.0

When I run the JuiceBox.app, I can't create a new gallery (clicking on New does nothing). I can't open an existing gallery, either (I can navigate to the directory, but nothing happens).

Any ideas how to debug ?

Thank you !
