Hi Andy,
the feature sounds very interesting. Could you provide us with more information about the capabilites of such a "calculator" object? Probably it would make sense to download OOFILE to have look at the implementaion? Maybe you could post a typical implementatin of a "calculator" object?
Thanks in advance.
Kind regards,
Carl
