1. Lock for Me will only be triggered after an app quits completely(Command + Q), then reopen. if you click 'close' button on the left top corner, that will only close the window, the app isn't quit, after that you open the app, Lock for Me will not be triggered.
2. For the files that can be open by multiple apps, for example, pictures can be open by Preview, iPhoto, etc. it's not a good idea to protect them using Lock for Me.
