                                with all Win32 versions (no longer needed separate
                                builds);
 0.12b    20070328  G.Tani      Minor visual updates for better integration with

 0.19     20080826  G.Tani      Ask path for saving reports, default is desktop (or current path if desktop is not found)
 0.20     20081026  G.Tani      Autosized/customisable GUI's items height; various graphic updates
                                Form_report that can now close the application if it is the only form needing to be shown
 0.21     20081118  G.Tani      appdata fixed for Windows users with names containing extended characters
                                filemode set to 0 before all reset file operations to avoid possible lock situations (i.e. concurrent instances)
 0.22     20091103  G.Tani      New icons
