Working Again
It appears the the last release of El Capiton had a slight issue with windows tidy. After a recent update fixed the issues I was having.
This app has been a favorite of mine due to how little it intrudes into the day-to-day life when you do not need it but easy to use when you do want to. Also the app has many adjustable settings to customize it to your needs.
