Thanks for your response. Just to clarify, I've been just typing in
the envi_open_file command into the idl command prompt, and have tried
a variety of different images.

I'm sure you're going to get better responses from folks more
knowledgeable on this than me, but have you tried using your script to
open a different file (to check for some kind of problem with
permissions)? Also, I would probably try using envi_open_file in a
different script and seeing what happens before I gave up completely.
Hope you get it worked out,
Jeff
