[Moonraker]

I use Windows 7 and would like to turn off the sounds Sigil uses.
i.e. The ding that is heard when I select "delete unused stylesheet classes" and a window message appears stating there are none to delete.

My reason is that I often do a live recording using Audacity. These can take some time so I usually work in Sigil during the recording process.
Having all these dings appearing spasmodically throughout spoils the recording.
