Hi Dzsoki,
I hope i understand what you like to have.
If you want to change the text in a Text Indicator and allways see the last letter, you have to set the Scroll Bar position to the bottommost line.
To realize that, create a Property Node of the Text Indicator /Text.ScrollPosition.
To be sure that the last letter is shown in the Indicator, the value for the property node has to be higher than the number of lines possible.
Hope that help,
Stefan Henke
