zipfile.py, fp.seek(-22,2) error

Hello,

I am new to Python. I am having trouble with zipfile.py.

On a Linux machine with python 2.4.2 I have trouble opening a zipfile.
Python is complaining about the bit where it does a seek(-22,2). Looks
to me like zipfile.py is trying to come back 22 bytes from the end of
file.

on a windows machine using python 2.4.2 zipfile.py works fine.

Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)]
on win32

IDLE 1.1.2
here is a windows machine using python 2.3.2 (cygwin)

$ python

seek doesn't mind going -22 from the end on a windows machine but hates
doing it on a linux machine....

any idears????

Thanks and Best,

ok, i figured it out. the file i was trying to read on the linux
machine was 0b. lol. i guess the "invalid argument" error was throwing
me off.
