IDLE Path doesn't include current dir after chdir

[Tom McDavid]

I'm trying to learn more Python and have come across a strange
behavior.
I have Python2.3 installed on a Win2K machine. If I start the python
command line, I can do the following:
Python 2.3.2 (#49, Oct 2 2003, 20:02:00) [MSC v.1200 32 bit (Intel)]
on win32
Type "help", "copyright", "credits" or "license" for more information.
## fibo is fibonacci example from tutorial.
Everything works fine. But with IDLE, I get the following:

Python 2.3.2 (#49, Oct 2 2003, 20:02:00) [MSC v.1200 32 bit (Intel)]
on win32
Type "copyright", "credits" or "license()" for more information.

IDLE 1.0
Traceback (most recent call last):
File "<pyshell#5>", line 1, in -toplevel-
import fibo
ImportError: No module named fibo When I use a desktop shortcut that has my start directory as
d:\python rather than the default, I can import my modules and things
work reasonably. I get the same "can't find module" result from
wxPython's PyAlaMode shell.
I dug a little and found that sys.path in idle doesn't seem to contain
".", when I manually added it, import behaves itself in idle after
chdir, but I don't want to have to manually fix my path every time I
start up. Anyone have more insight or a fix?
Thanks,
