Odd. Mine doesn't do that. You're using the WM6.5 new lock (slide to unlock) and you're not using any other locks like S2U2, etc? Do you have any taskbar customizations in place? I'm tapping all over my screen with this thing locked and I can't get it to make a sound. Then again I've done a series of sound customizations as outlined in the first page of this thread. Maybe someone else can duplicate it? I know I've heard this once in awhile, but it was very rare (once a month, perhaps). Very frustrating indeed.
