Hi all, If you have a second, I'd really appreciate your help with figuring out where Tkinter is available: inside the TeraGrid, on your personal machines, on other supercomputing centers, etc etc. This form: http://spreadsheets.google.com/viewform?formkey=dEhzZXdTbl9ydDJXb3JYSktEd2J3... will collect your responses, and it describes what to do. You simply have to run the command: "python2.6 -c 'import Tkinter' " and report if it throws an ImportError or if it passes without failure. Thanks very much, and I really appreciate you taking the couple moments to do this. -Matt
