Err... I'm sorry I don't understand your problem here. You don't plan on
sticking to 2.3.5 forever, aren't you ?

*please* re-read carefully what I and Diez wrote earlier in this thread
before jumping to possibly erroneous conclusion. I didn't say that the
problem *actually* was with Python - just that it *may* have to do with
a memory management issue fixed in 2.5. And, while we're at it : your
application uses a GUI toolkit and does image manipulations, so the
problem can also come from one of these packages...

I also suggested that it may have to do with your code keeping
references to objects. del' an object just decrease the reference
counter - the object won't be freed until there are no more reference to
it *anywhere*.

If I was in your place, I'd *really* make sure the problem is not in my
code. Like, amongst other things, installing Python 2.5 and testing the
 program with it...
