Dear Eric I'd just like to 100% agree with you and hope that someone from MI is taking notes. There are loads of new and at first glance impressive features on version 6.5 -many of which I have never used - but the ability to georeference accurately to give professional looking final images (without scalebars/grids skewed and so on) would be very useful. By the way, to add to your wish-list I would like the ability for MI Pro to take old images that have been registered in MI (I have hundreds) and transform them, using your points, without having to re-register the whole lot!! - I know there are loads of other packages out there that will georeference brilliantly, but unlike you, we can only afford one major package so I am afraid we are a bit stuck (with MI Pro).
