Platform: Ubuntu 8.10 Affected versions: Python 2.6.2, IDLE 2.6.2 and Python 2.5.4, IDLE 1.2.4 From IDLE I run a program that opens a graphics window (e.g. using the Natural Language Toolkit: >>> import nltk followed by >>> nltk.download()). When I close the graphics window, I expect to be able to continue working with the Python shell. What happens instead is this: The graphics window closes, but the shell prompt (>>>) does not appear. It seems the subprocess responsible for the graphics window is still running even though the window is no more. All I can do is close IDLE upon which it complains about a program that is still running. I am not sure whether this is an IDLE-bug, a graphics package bug or a nltk-bug,

Surely a graphics program should be run from a command prompt, not from IDLE or anything similar? Hence can this be closed?

This issue can be closed. The natural language toolkit uses Tk for its GUI, the same as IDLE. Under Ubuntu 8.10, IDLE is launched from the menu without a subprocess. Running nltk as described without a subprocess causes this problem. Try launching IDLE without "-n".
