The standards committee is currently discussing the kinds of changes that can be made to the standard. A virtual function, no matter how erroneous, is still part of the published interface to a class. If it shouldn't have been virtual then document that it shouldn't be overridden. But don't break users' code. They won't forgive you. More important, if they decide they can't trust you then you won't sell to them in the future. -- Pete Becker Dinkumware, Ltd.
