Yes that's right, that wouldn't work in that case. Then one solution would be to save the text property when you know it's below the limit (for example in the TextInput event), then in the CHANGE event, check the text height again. If it's above the limit, restore the previous text property. You might also want to save and restore the caret position as well (see selectionStartIndex and selectionEndIndex)
