IDLEfork 0.9a2, Python 2.2.2, Windows XP
I was documenting another case of Tkinter freeze by
adding a doc comment in an Editor window when I found
that the backspace key will not erase a line beginning
with >>> followed by a space. That is,
"""
Pressed F5 to run
Example window appeared
Clicked button
>>> appeared in Shell window
... more comments
>>>
...more comments
"""
When I attempted use backspace to delete the ">>> "
line, the cursor refused to move leftward. Pressing Home
and hitting the Delete key 4 times works fine.
Two things to think about:
1) The syntax highlighting indicates the cursor is in the
middle of a comment.
2) This occurred in an Edit window, not a Shell window
FWIW, this defect is hardly worth mentioning. But, if
IDLE is a tool used by beginners, these odd behaviors
undermine confidence. When I encountered this defect,
there was a period of 10 seconds when I thought
IDLEfork locked up - the backspace key just wasn't
working.
