Rick,
Yes trying everything on unix takes time and all you will get out of it is a
little more understanding on how IDL is coded internally. I thought the same
spook that causes the IDLDE to be unresponsive is the origin of your update
problem. (I still want the unix-like command line version in Windows, and
damn it, I forgot to put that on the final beta questionaire.)
