Hi Pat, Your tips seem to work, but I am hoping you also know the answer to the next problem. See example 1 : After replacing the text with ST SET TEXT($wp_obj;$text;$start_pos;$end_pos) the cursor must be set after the last inserted character. This replacing is done in the On After Keystroke event of the Write Pro area and is triggered when the user types a space. However, I don't succeed in setting the cursor at the end of the inserted text, it stays at the position where it was (position after the original space)
Do you also have a tip how to set the cursor to a different position in the "On After Keystroke" event of the Pro Area?
