Thanks for your help David!

I'm an IDL novice, so the first thing I did was tab after xroi in
emacs to find the x/y_scroll_size option and tried them out. This
solves one problem (the window was too big) but it doesn't do what I
really want -- which I didn't make sufficiently clear in my original
posting.

I wish that xroi showed a scaled version of my image, not just the
image at maximum size with scroll bars set so it fits on my screen.
The issue is that I want my users to be able to see the entire
(scaled) image on screen and make a simple ROI cut. It's possible
they could muddle through it with the scroll_size option set small
enough, but it would be nicer if they could see the entire image.

Thanks again,

stephen
