[comp.sys.mac.hypercard] Using "select" in scrolling field

LB7@PSUVM.BITNET (Lorinda L. Brader) (11/04/89)

I have developed a stack (HC 1.2.2) in which I need to hilite the line that
is clicked on in a scrolling field.  Sound easy enough, however, HC acts very
inconsistently in this type of situation.

If the scroll of the field is 0 and I click on a line I can hilite that line
very nicely using the "clickline" function and the command "select line clicked
of field".  However, if I scroll down in the field, click on another line and
use the same command, the line is hilited, but for some reason the hilited line
is moved off the visible part of the scrolling field and you must scroll down
to see what has been hilited.

I've temporarily solved the problem by unlocking the field and using a click
and shift-click combination at the clickloc to hilite the line clicked on.
Because of some new developments in this particular stack, I would like to be
able to use the "select line clicked" command to hilite lines in a scrolling
field.

Is this a bug in HyperCard or does someone know of a way to solve the jumping
out of view of a hilited line using "select" in a scrolling field.
