• Visual C++ Dialog Resizing in Japanese XP

  In an 8-year old MFC/MDI project under Visual C++ 6.0, I use the default 8-Pt. MS San Serif.  For the first time I have heard from a Japanese XP customer that the dialog is being resized and labels are being shifted and/or truncated.  Experimentation showed that I could easily reproduce the behavior just by changing font dialog.  I assumed that XP was replacing an unknown font with some more universal font.  However, 8-Pt.
