On Macro Security Level "High" and "Very High", when you open a document
containing macros, which are not executed due to security settings, this is
announced to the user with a modal message box. This box is annoying and
interruptive, and most probably not necessary at this point.

I suggest it should - if at all - appear at the moment a macro is really
triggered (and prevented from execution), since this is the point in time where
the user needs to know about it.

fs->flo: I took the liberty to submit this to you, as you're the owner of
http://specs.openoffice.org/appwide/security/Electronic_Signatures_and_Security.sxw.
In the respective chapter in this spec, there's a note saying "We need to have a
configuration entry to suppress this dialog (no GUI needed).", which lets me
assume that the need to suppress this dialog is known :)
