While running your program and using a keyboard where catchall is set to 0, when i button mash and have the desktop active, Windows makes a ding sound.
Checked process manager and it says windows made the sound from creating and deleting a file?
If you where using numpad did you enabled Numlock? When numlock is disabled then there is Insert and Delete button under 0 an ".". Maybe this was the problem?
