You need to use the (non-standard) Full Screen command in the Options menu, or its keyboard shortcut cmd-F. I imagine that the next version will do the right thing when you click the standard green window button.

Fixed in 2.4, thanks for testing it kklobe!

A number of issues relating to this have been fixed recently, but are not yet available in the regular releases. Please try out the current pre-release beta and let us know how it works for you!

Just a minor update:

• Prevented Speech errors from causing an abrupt quit.
• Slightly lowered monster spawn rate.

The Discogs.com reply you received isn't quite correct. When support for Discogs.com was added to MPFreaker, it was with their (then-current) JSON API, fully respecting their terms of use and usage limitations. MPFreaker has never "scraped" from Discogs.com.

• Support for Album Artist vs. Artist inconsistencies • Added Newest Date Added and Oldest Date Added to Audio data automarking preferences • Added partial French translation • Improved missing library handling • Better behaved when working with libraries containing tracks in iCloud • Fix for issue ...

Paul, 1.4 and later have more verbose internal logging of information relating to this issue (because of your same question in September). In 1.4, please perform a small test in which you encounter this problem, then send the resulting Song Sergeant log file to songsergeant@lairware.com. The log fil...

One would therefore need to go through the duplicates list and manually ensure that the oldest Added audio data is ticked for each set of dupli...

I should note that this has been resolved via email. In Song Sergeant's "Inconsistent" renaming process, it isn't able to rename tracks that are only available on iCloud (via "iTunes Match") and are not present on a normal file system (local or file server, for example). This will be resolved for th...

• Fixed persistent crashing with extremely large libraries (now a 64-bit app). • Developer ID code signed. • Improved Retina support. • Other minor tweaks. We are working on getting Song Sergeant 1.4 accepted on the App Store, but there is a chance it will rejected because of Apple's increased rest...

This will definitely be addressed in the next version. No ETA for that, however.
