I have a similar situation with APL*Plus/PC.  The APL interpreter makes use of
a number of symbols not ordinarilly seen on an ASCII display, and does so by
means of a "soft" character set, i.e., one loaded into memory.  The APL
characters come through fine when the interpreter works in full-screen but not
when it's reduced to a window.  In this case I see the "normal" ASCII
characters (and since many of the APL symbols are in code positions occupied by
graphic ASCII characters, those are what I see).  I haven't taken the trouble
to see whether it's an APL bug or a Windows bug since it doesn't really bother
me and I view it as a temporary problem.  At any rate, your experience sounds
like it's the same bug.
