That worked extremely well -- thank you! Very clever use of the
formattedheight.

I have a field full of (locked) text (a TV script), lines are wrapped. I want

I can set the vscroll of the field using the number returned by (the
clickline)*(the textheight) of the field. But, each wrapped line in the text
above the click throws that calculation off...
How can I take the wrapped lines into consideration so that the text my users
click pops to the top of the field?
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
