[New-bugs-announce] [issue25662] _tkinter.TclError: bad event type or keysym "Alt"

[Chesqa Yen]

New submission from Chesqa Yen:

For a while now my python IDLE has not been working, mostly due to me trying and failing to reconfigure the button assignment to tailor me. Now when i try to open idle it does not open. I tried using some sites for help (http://www.gossamer-threads.com/lists/python/bugs/901999) which had a similar error however, even with a new config file it still wasn't working. Please could I get some help as I need python running on my laptop to do my university coursework. I've attached a file with the error message from cmd.exe and will paste it again;
