Left handed leaders in V5 have right justified text by-default and, as far as I can see, are not adjustable. When the same V5 leaders are opened in V6, the text becomes left justified by default, so needs to be adjusted back to right justified.
V5 wrapped text becomes unwrapped when opened in V6.
In the Dimension properties panel, maybe the info boxes at the top could be aligned with the rest of the edit boxes below, see image.
