itself appears to be working; if I un-comment the "Cut()" at the end, I
click into the box and the existing text disappears. Without the Cut(), if I
click into the box, the caret appears at the end of the existing text, the
text is NOT highlighted (as in Ctrl-A, which works fine), and typing just
appends to the existing text. Any clues appreciated. I've been trying to get
this working for several days now, and everything I've found seems to
indicate this should work.
