When I enter a letter, the TextChanged event is always triggered 2 times, once with the correct NewText and the 2nd time the OldText is in the NewText. Why is this so?
I did not notice this before.

Example is attached

Private Sub TextField1_TextChanged (OldText As String, NewText As String)
    Log("TextField1_TextChanged " &  OldText & " -> " & NewText)
End Sub

Private Sub TextView1_TextChanged (OldText As String, NewText As String)
    Log("TextView1_TextChanged: " &  OldText & " -> " & NewText)
End Sub

It doesn't happen here. Are you testing it on a real device?
