When attempting to save a file containing an Å character with the debugger open, IDLE freezes with/or without partially opening the warning window. (Mac OS X 10.9.5, IDLE running python 2.7.5). Reproducible steps: - Create and save file with one line: 1+1 # A - Open IDLE - Open the debugger - Open the file - Delete the "A", type A - type s to save. This triggers the problem. Application hangs ("not responding") and needs to force quit. Sometimes the graphics memory of other applications gets corrupted.

Thanks for the report. It appears that all that is needed to trigger the hang is any operation that invokes the IDLE EncodingMessage dialog ("Non-ASCII found, yet no encoding declared. Add a line like [...]") in IOBinding.py during a Save when IDLE is linked with the OS X Cocoa Tk 8.5 (or likely 8.6) as used with the python.org 64-bin/32-bit 10.6+ installers, for example, just opening a new edit window, inserting a non-ASCII character, and then trying to Save. EncodingMessage subclasses the Tkinter SimpleDialog module and creates a new Toplevel root; I seem to recall other problems like this in the past. The problem is not seen with the older Carbon Tk 8.4 or with an X11 Tk on OS X.

I am no longer patching IDLE for 2.7
