Thanks. I was afraid there was some sort of hard-coded limit like
that. Looks like it's time to scrunch my caption text.
I find it ironic that with all the concern for backward compatibility,
the concept of the 80-character-wide screen has been completely
abandoned. ANSI_FIXED_FONT doesn't quite fit a 640x480 screen either.
Sigh...

Windows paints the title bar in response to a WM_NCPAINT message (along with
the window frames, the system button, and so on). Inside the DefWindowProc
code that handles WM_NCPAINT messages, the code calls GetWindowText to get
the windowÉs title string. In this call to GetWindowText, the size of the
buffer (the third parameter) is only 79 bytes. This limits the length of a
windowÉs title to 79 characters.
