It is the same as above case, when I > click the 'Start McIDAS' button. Please let me know if a configuration gui pops up when you start using 'mcidas -config'. The default for my McIDAS GUI interface, MCGUI, is to only run the configuration widget if the user specifically asks for it to be run using 'mcidas -config'. > I am including screenshots for the two cases.

So far, I have learned that I am unable to launch the version of 'wish' that was installed as part of the operating system; the error message was the same. I am able, however, to launch an xterm with display back to my machine (using 'ssh -Y') and then launch the version of 'wish' built as part of the McIDAS build: <logged in as 'mcidas' using 'ssh -Y address@hidden'> xterm & -- from the xterm that popped up cd ~mcidas tcl/bin/wish8.4 This is obviously telling me something important about what has to be done in order to run programs, I am just not sure what it is yet :-( I will keep researching...
