It is not necessary to stop Browsealoud. You can continue to perform other tasks on your computer, while Browsealoud runs in the background. However, you may not want Browsealoud to start immediately each time your computer starts. If this is the case, you can deselect the Always start Browsealoud when my computer starts check box in the Program tab of the Browsealoud Options dialog box and then manually start Browsealoud when you need to use it.
You can also stop Browsealoud at any time by right-clicking on the icon in the system tray and selecting Exit Browsealoud from the popup menu.
