Thanks for the report. Python 3.1 only gets fixes for security bugs now, could you try to reproduce your bug with Python 2.7, 3.2 or 3.3?

I tried to reproduce it on 3.1 and 3.2 but it worked fine here (WinXP).
This is what I did:

1. open IDLE;
2. file --> new window;
3. write some text;
4. select with the mouse some text;
5. press shift and keep it pressed;
6. press end;
7. press home;
8. release shift;

I also tried in the "Python Shell" and releasing shift before pressing end and home, but I got the same result. Shift+end highlights till the end of the line, shift+home till the beginning.
