I think this will work: set the "cursored" attribute on the record. Then move
the highlight up and then down using "keystroke sending." If you test it
out, you will see that OS/2 has no problem allowing the "cursored" record
to go out of view (you can prove that by scrolling the container up and
down while a record is cursored). But it will display the record if it gets
an "up arrow" keystroke. You then move it "down" again so as to put it on the
record that you actually wanted highlighted. For more information on
sending keystrokes, you can see the technote on it at
http://www.watcom.on.ca, or the docs for SendKeyString and the KeyString
property.
Good luck!
