I'm using Windows 7, Python 2.7.2.
Before the problem occured, I've been writing code in IDLE(Python GUI) for 30 min and everything's fine.
Then I went into "IDLE configuration" and changed the settings to the following states: 1) When press F5, don't show the prompt "save or not'. 2) Upon start, show editor(instead of shell);
Then I close IDLE, and clicked the IDLE(Python GUI) icon(from the start menu), and no window pops up...
However, I can start "Python(command line)" without any problem.
Have tried uninstall - reboot - reinstall(both python 2.7 AND 3.2 had been tried), but the problem persists.
Any ideas why this happened?
