[Qgis-user] QGis suddenly started to emit a sound....

[Alessio Degioannini]

QGis was working normally, as always, since I've loaded a vector layer.
Then it started to emit a strange low tone: on panning, on digitizing 
(points, arcs, polygons), on editing and on every movement of the cursor 
(2 sounds for every single movement).
I can't understand what is happening, but it drives me crazy!!
Help, please!
