Interesting, appears to be a feature since Windows 7. TBH, I migrated to Gnome 2 back in the days of Windows XP, so never noticed it. Thanks for the tip!
Yeah, it was there in Windows XP too. Though TBH this assumes an application uses the native dialog box for messages and many applications make their own. For example Delphi (at least the older ones) applications do not seem to support it. However some applications may implement it themselves (e.g. Lazarus does support it but it uses its own formatting).
Heh, then I could easily say the same for the lack of regexp search/undo tree and so on in text boxes. When will Windows ever add those functionalities? Extensibility really makes all the difference. Emacs is perhaps the most successful Lisp machine.
