ddd debugger ignores breakpoints

[Jens Wolk]

Hi everybody,

on a RedHat 7.3 system I try to get ddd working for me as Python debugger.

Versions (out of the box versions of the RH distribution):
Python 2.2
ddd 3.3.1

I do so by starting the debugger with
   ddd -pydb

Then I select File->Open Source ... and navigate to an sophisticated (tm) 
hello.py which contains the following lines:
print "Hello World"
print "Hello World2"

On both lines I set breakpoints and then hit "Run"-"Continue"-"Continue" ... 
and the complete code is executed without stopping at a breakpoint. Why is 
that so?

BTW, I evaluate ddd because I didn't find a way with pdb.py to display the 
line which it will evaluate next (and some lines before and afterwards, 
preferably). Is there a way to do this?

Any hints are very welcome.
