Summary: .py file "IndentationError" corrupts appearance

Initial Comment:
Opening a .py file like the one attached causes a long 
stack trace to appear in the Interactive Window 
(appended at base of this description), and a number 
of strange characters to appear in the script window 
(particularly breakpoint characters on every line).

The file must have triple quotes at the top, some kind 
of code construct like a class or a file with a triple-
quoted doc string who's second line is indented. For 
example:
---Start---
"""
"""
def foo():
    """This line is fine
        This line makes PythonWin unhappy.
    """
    pass
---End---

Removing the triple quotes from the top of the file 
makes the problem vanish. Removing the second line 
from the function doc-string also makes the problem 
vanish.

Tried on Windows 2000 installation built from source, 
and Windows XP SP2 installation installed from 
ActiveState.

This no longer occurs with recent builds.
Not sure at what point it was fixed, though.

To see the problem save a file with the code, then re-open 
it.

Apparently follow-up posts get to keep indentation, so 
here's hoping:
---Start---
"""
"""
def foo():
    """This line is fine
        This line makes PythonWin unhappy.
    """
    pass
---End---

Unfortunately the code loses indentation inline in the 
report, so use the attached indnterr.py file to see the 
problem
