Changed title based on 'command line works fine'.

You might try running test suite, 'python -m test.regrtest' from Command Window in python27 directory on both this and other system. (It takes about 20 min, so minimize and do something else.) test_tcl, text_tk, and test_ttk fail even when IDLE works, but maybe something else, not normally failing, will fail on this system (and not on one where IDLE works).
