The background helper is enabled by default; this launches a background process to monitor URLs so that it doesn’t interfere with the main app.
Launch the Hubstaff application. Click on the options (menu) icon on the upper-right hand corner of the app, then a menu will show up.
Click on Preferences. In the preferences options, you can enable or disable the background helper by clicking on the checkbox. You’ll need to restart the app for the changes to take effect.
