#15 1.3a1 fails to start under Windows XP

others (11)

I have Windows XP (with SP1) installed, Python 2.2,
newest wxPython and pyXML. I install all that and try to
start pyut (pyut.pyw), the splash screen appears and
shortly after that i get a windows error box saying: 'The
following error occured: C++ assertion "wxAssertFailure"
failed in e:\projects\wx\src\msw\treectrl.cpp(749): can't
retrieve virtual root item'. I can only press 'OK' and the
app is closed.

    Could you be more explicit and tell me exactly which version
    of wxPython you have and give me the complete error trace ?

    At first view, this seems to be a wxPython error.

    I have the same error with PyUt 1.3a1, wxPython,
    Windows 2000 Pro SP3.
    There is no error trace... The error message is displaid in
    a "popup" window titled "An Error occured...". Seems to be
    related to the version of wxPython ?
    How can I help you more ?
