Whatsize.exe is a Petzolds example which tries several MapModes using a SYSTEM_FIXED_FONT.
Oddly, seems MapModes are broken and just MM_TWIPS seems to be working (while MM_ANISOTROPIC or MM_TEXT are broken).
Hint: When resizing the window, seems some text is written and repainted, but the position of the text is always behind the MM_TWIPS printed line.
Katayama Hirofumi MZ probably can share his knowledge in this report to point the real issue behind this bug.
