                                    left/right arrow keys were supposed to expand/collapse the current selected node. It wasn't working before, but I just fixed it, maybe it also fixes this issue but I'm not sure.
The title of the readme file clearly states **MS** Map Compiling Toolkit, and it's also mentioned in the repository details, but I guess we could add a bigger disclaimer on...
I know this is kinda old, but I had the same issue. To fix this, make sure to actually install your application on your Organization.
