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, /Valur "Bojan Bistrovic" <bojanb at physics.odu.edu> wrote in message news:87mt7d$7id$1 at dragonfly.wolfram.com... > > Hello, > > I have this problem with Mathematica 4.0 .
