When wrapping text, the text moves up when the text field is shortened.
This goes against logic.
It would make more sense if the text moved down when the text field is shortened.
Hi Emil- the text will move up if the base point is at the bottom, down if at the top, and both if in the middle. The base point is at the bottom by default I think, but you can set it in the Text dialog, or afterwards modify it in Properties > text page.
Does that help at all?
