Some helpful info:
If the tools are freezing on Mac, or you're having problems in that vein, TRY THIS! There's a security issue on OSX, where if you download the authoring tools from online, and they're still in your download folder, they won't work. You simply need to move the .app file somewhere else (to your desktop, say), and then this problem will be fixed.
One way to help track down bugs in the platform is by accessing (and sharing) the log. If you're using the standalone authoring tools on Windows, you can find the log here: “StudyCrafter_Data\output_log.txt”. If you're on Mac, you can find it here: “~/Library/Logs/Unity/Player.log”. For more information on accessing the player logs, click here.
Aside from helping with Debugging, the output log also contains some useful information, like written out transcripts of the scenes (which are written into the log file when you play each scene).
Currently, the authoring tools save your changes whenever you switch between different tools (layout, script editor, player, menu pages).
