You can try to add the conzole (yes with a z) library to your html...
...Unzip and copy both files to your '/Shared Files' folder. It should show you something like this and you may see some other errors that can help you identify the problem:
Hey, AB, thanks for that! Upon my first attempt, after placing those files in the Shared Files folder, it still did not work for me.
However, yesterday, I remembered having to drag a file to the "Files Manager" tab in the IDE before it would work. I tried that with conzole.js, and now the Conzole window appears! However, nothing else does. It's a blank view. So, I think the app is not seeing everything else in the B4J/Files folder... namely, the other three folders.
The programming gods hate me.
If I get an error in the IDE log that says, "Asset file not found: editor.html," what should I do about that? That file is in the Shared Files folder, and does get placed in the B4J/Files folder upon app start-up, so I'm not sure what's going wrong here.
