Just tested it: two revisions. If the textheight of the field is empty then the
original handler won't work, so use "the effective textheight of me." Also,
correct for the borderwidth of the field:
on mouseup
put word 2 of of the clickCharChunk into chNbr
put the number of words of char 1 to chNbr of me \
into wordNbr
put the formattedheight of word 1 to wordNbr of me \
into upToHere
put the effective textheight of me into txtHt
put upToHere - txtHt + (the effective borderwidth of me) \
into upToHere
set the scroll of me to upToHere
-- so the line remains visible
end mouseup
