Well, it's unclear exactly what you mean by "until the user
selects/highlights a text cell for the SECOND time". Does that mean that if
the user just taps twice in succession on the same cell, you see the error?
Or that the user taps on one cell, then on a different cell, then back to
the first cell and then you see the error? Or does it require that the "OK"
button be tapped somewhere in the sequence before the error shows up?
I took a glance through the code and I don't see an obvious error. But
without knowing the specifics of what causes the error to show up, there's
not much I can do, other than suggest standard debugging practices like
comment out the call to FldSetSelection to see of that makes the error go
away.
