I've got a bad supertalk problem.
What I want is to have a scrolling window with two fields inside which, when
clicked at, the line being clicked at changes its text style to bold.
After some digging, I found that I could change the text style of portions
of a field by selecting the desired portion, then changing the text style
of the field.  Only the selected portion is affected.  Great.
The only problem is that I find out what line was clicked by using a list
field, which apparently doesn't use selections at all.  When you select text
in a list field using the select command, nothing happens.  I also can't
use regular, non-list fields because I need to find out the line NUMBER being
clicked (I can't use the method of double clicking at the location of the
cursor).  The only way I know of finding the line number being clicked at in
a regular field is to use a hypertalk function called clickline.
This won't work because when it tries to get the textheight of the field,
supercard returns "mixed" rather than a number.

Any help would be greatly appreciated.
