This is fairly characteristic of all filmscanners, to a degree at least. 
Have a close look at some of the native resolution samples for different 
scanners at my site. I don't believe it is chromatic aberration of the 
lens system (which would reverse across the frame) but simply 
colour aliasing compounded by perhaps some CCD blooming.
