I think this problem can appear when you use getc() and don't include
<stdio.h>. If you don't, you will be using the C library function, that
does it byte by byte, but <stdio.h> contains a macro for it that uses
a buffer... This is from experience with UNIX, not MiNT though.
Might be worth a look. ;-)
