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.

I am using a Mac SE with a Radius Accelerator board, HC 1.2, and System 6.0.1. Old versions of the LW+ fonts had screwed up FOND resources, which have important font width information. I would get a recent version of Font/DA Mover, like 3.8, and get some recent fonts and try reinstalling the fonts. No problems here! Dan Allen Apple Computer
