Are you saying with gc.collect it now can create some?  If yes, then you 
need to put more calls do gc.collect.

I assume you changed this:

if runningPlatform[0] == 6: # Testaa onko Windows 9x
to something like this:
if runningPlatform[0] < 4: # Testaa onko Windows 9x

I am not sure what the version number for WinMe and/or 9x, but I think 
if you use " <4" you should catch anything before Win NT.

See above, make sure that you use a version which includes ME, so 
gc.collect is run.

This is a totally different problem.   I think this could be fixed by 
changing your default encoding to something other then ascii.

I do this in my wx.App module:
if hasattr(sys, "frozen"):  #Py2Exe does not run Site.py
    sys.setdefaultencoding('iso-8859-1')
    del sys.setdefaultencoding

I don't think this is the case.  Otherwise why even bother having py2exe 
- BTW, which version of py2exe are you using?

Yeap, this is more like it:)

If you still have problems I suggest that you create a small sample 
application which shows the problem and post it here together with your 
setup.py.
