Instead of using focusOut and focusIn I
used keyDown and mouseUp and that seemed to do the trick. It may not be
perfect all the time, I’d imagine you can type fast enough and maybe
confuse it, but this should get you going.

The Selection.getCartIndex() doesn't seem to work,
I've tried to call
it when I loose or gain focus within the textArea
control.
Irrespective of where the cursor is within the
text area the
Selection.getCartIndex() seems to return
"0" or "-1"; naturally there
is text inside the text area.
Do you have an instance where it's been used
correctly, I been through
the MM web documentation and have failed to get it
to work.
I include my test bed. Am I using it correctly?
