I am not seeing this happening just on text which is updated by actions. I am seeing this happen on every instance of text which is set to render as an image.
MattK said:When I select "Render text as image when published", this version of Lectora seems to add an image of up and down scroll thumbs even when the text box is plenty large to accomodate the text. Is there any known workaround for this problem to allow text to be rendered as image in 9.3 without the scroll thumbs?
