There is a new version of look.pro at
http://idlastro.gsfc.nasa.gov:80/ftp/contrib/knight/look.pro
The file is about 121k long, so I attach an excerpt from the header below. The
new version has a number of improvements, including improved sliders, better
catalog/blink/movie selection, intrinsic Postscript printing, and better help.
As always, I appreciate feedback---either pro or con.
