I just noticed something weird when using this app. If MStarDict is running, the pulseaudio process is taking 20% CPU all the time (which drains the battery), even if I didn't use the "Speak" button even once. When I quit the app, the pulseaudio process goes to sleep immediately.

Why does a dictionary actively need the sound process? Am I the only one who've got the problem? Should I file a bug for this?
