There may be a module in your system path that shades one of the modules 
needed by idle. When you start idle with the GUI the working directory is 
probably your home directory. (If you can import os use os.getcwd() to 
verify) This is just guessing, but the first thing I'd try is to remove all 
Python files from that directory (and also the *.pyc/*.pyo).
