wxPython installation interferes with win32ui/win32gui

[robert]

As soon as I install wxPython on a Py2.3.5, my win32ui / win32gui apps 
freak out. buttons in dialogs are magically pressed. backgrounds of 
dialogs are colored wrong...

this is with current wxPython (it was the same situation with a wx 
version some months back)

When I uninstall wxPython the other win32ui/win32gui apps work again.
What could be the reason?

I made a full file comparison in the c:\Python23 tree: wx installed vs. 
wx uninstalled. Besides the wx things in site-packages only ..

c:\Python23\pythonw.exe.manifest
c:\Python23python.exe.manifest

.. and things in "c:\Python23\Scripts" are written/changed. nothing in 
site-packages/pythonwin and site-packages/win32*  is changed by the wx 
installer. Or does the wx installer change something in the DLL's in 
\windows  or worse...?
