I don't get the same thing on win2k

F:\Python22>python
ActivePython 2.2 Alpha 2 build 1 (ActiveState)
Python 2.2a2+ (#22, Sep  5 2001, 14:10:41) [MSC 32 bit (Intel)] on win32
>>> class Test:
...     def __str__(self):
...             print "in __str__"
...             return "str(self)"
...
>>> test = Test()
>>> print test
 in __str__
str(self)
>>>


I do have other flakey additional/missing line space problems when not
directly running from the dos command prompt, more with win2k it seems that
with win9x.

But I don't know where the problem is.  ;-)


ps.  ms outlook express spell-check wants to correct win2k to <wink>  ;-))
