Yes, using Python24 and the latest win32 build on my machine the bug
still exists. PythonWin works fine if you don't use the debugger.

But since the debugger is the most valuable feature for me I sadly had
to stop using PythonWin. For a while I found some help by running the
script below every now and then. It deletes the erroneous registry
entries. But currently the bugs are stronger.

Here's my solution: I spent some money and switched to "WingIde" from Wow, it's breathtaking and worth each penny. Don't
compare WingIde with other editors. WingIde really plays in the IDE
(integrated development environment) league. And it's very Python
aware and knowledgable ...

Here's my script to delete the erroneous debugger entries:

Script "delete-debugger-entries,pywin,"

#!/usr/bin/env python
# -*- coding: iso-8859-1 -*-

"""Delete problematic registry entries in 'Python for Win32'.

No warrenties whatsoever. Use at your own risk.

import win32api
import win32con

subKey = r'Software\Python 2.4\Python for Win32'
subKey = r'Software\Python 2.4\Python for Win32'

if 1:
    #HKEY_CURRENT_USER\Software\Python 2.4\Python for
    k =
    nsubkeys,nvalues,timeval = win32api.RegQueryInfoKey(k)
    keys = []
    for i in range(nsubkeys):
        s = win32api.RegEnumKey(k,i)
        if (s.startswith('ToolbarDefault-Bar') or
    for i,key in enumerate(keys):
        subKey2 = subKey + '\\' + key
        print i,':', subKey2
        if i>99999:
    print len(keys),"deleted."
