HI, since this morning Mail plays a new sound. Everytime I start the program I get a sound I've never heard before, this sound is not one available in the Mail's or the system's preference. Maybe some of you have heard this sound, it sounds like a sword striking the air, it gives two strikes on the right speakers, then 2 strikes on the left speakers and it finally ends with a tap on a high pitch bell. I tried to inhibit system's sound and mail sound and I still get it to play. thanks for your help.
