I've recently noticed some minor bugs when I have a HyperCard 1.0
field using a largish (18 pt?) size of Zapf Chancery (my favorite
non-roman font).  Specifically:

(1) If a lower case 'j' is the first character on a line, most of the
    descender doesn't show on the screen.  It appears to be getting
    clipped to some inner bounding rectangle of the field.

(2) If you're typing into a field, and you type a 'j' and then backspace
    to delete it, sometimes (depends on preceding text, i.e. probably
    varies depending on exactly where the 'j' falls) a piece of the
    descender is left there.  This is purely a display bug; if you
    go to another card and then back it's not there.

HYPOTHESES:

	There is a bug in the description of 'j' in that size of
	Zapf Chancery, -or-

	HyperCard is taking some shortcuts that don't quite work,
	perhaps in the backspace code, -or-

	There's an underlying bug in the toolbox that this exposes.

To reproduce, make an appropriate field and type in:

j<RETURN>
Sj<BACKSPACE><RETURN>
Saj<BACKSPACE><RETURN>
Sanj<BACKSPACE><RETURN>

and then hit arrow keys to go to the next card and back to this card.
