An incredibly irritatinge 'feature' of Mathematica 4.0. A workaround (not sure of
possible unwanted sideeffects) is to select Edit -> Preferences... from the
menu, lookup GlobalOptions->MessageOptions->"WarningActions" and unselect
Beep. This means that Mathematica will not beep at you when any event triggering a
warning occurs, including the one arising from the use of brackets involving
AltGr.

Hope this helps,
