For the past day or two when I double tab(or double click) to open a file or even play a song on Spotify, it doesn't work. I checked the trackpad prefs., better touch tools prefs, and xtrafinder prefs, and still can't figure out why double tap isn't working. I even had those 2 apps not running and it still doesn't work, so I know its not that. Its annoying since now I have to press cmd+down arrow to open files, double tapping just makes it so I can edit the filename. What could have I have done to change that?
