Jennie,

If you wanted the 7.60 version of .mcidasrc, you should have moved
the old file to .mcidasrc71.  Copying it leaves .mcidasrc in place,
and McIDAS will not overwrite .mcidasrc if it exists in the user's
HOME directory.

>Anyway, the error I get is :

This is caused by 7.60 not being installed yet. The Tcl/Tk stuff (i.e.
GUI stuff) will not run until the installation is complete.  The reason
for this is that the Tk routine 'mcwish' has the location of shared
libraries "burned" into it.

Apparently, your .mcidasrc file says to bring up MCGUI automatically
upon start.  My testing procedures tacidly assume (apparently
incorrectly) that the GUI stuff will not be run during the test.  I
guess that I should change the documentation to tell a user to bring up
McIDAS specifying a different defaults file that does not exist.  This
would prevent the GUI stuff from being run.

Right.

Right again, but I wasn't taking into account a user specifying automatic
startup of MCGUI (or GUI) in .mcidasrc.

Right.

You are correct.  It is no big deal.

>I decided to try it again, and this

You are correct.  I will have to remember to address this in my
documentation.
