That's correct. We'll fix this that in Advanced Mode it won't show the program window even if there is no volume configured.
We'll also add a changelog.txt in future releases. Here's the changelog of v1.3.2:
* Modified: Restrictions in free version (e.g. no folder size limitation anymore)
* Modified: Upgraded to the latest CBFS version
* Fixed: BoxCryptor crashed when a file in the BoxCryptor Folder has been changed outside of BoxCryptor and path length was > 260 characters
