[python-win32] win32api.FindFiles hangs

[Boylan, Ross]

The problem doesn't seem to be python-specific; it appears the underlying FindNext function in the Windows API just keeps returning the same file name instead of moving on.

In VBA in Access 2010:
Public Sub test2(pattern)
    Dim fn As String
    fn = Dir$(pattern)
    Do While fn <> ""
        Debug.Print fn
        fn = Dir$()
    Loop
End Sub

When I execute with test2("Z:BSTImport.py") this loops, apparently  forever, with each iteration returning BSTImport.py.  If I give it *.py as the pattern it prints 2 files (correctly) and exits.  I assume the first call to Dir$ does FindFirst and the later ones do FindNext.

Using the complete path name doesn't help.

This seems both bizarre and a sign that my installation of Windows (not python for windows) is pretty messed up.

Works just fine on my windows7 machine with python2.7 64bit and
pywin32-221
It yields results for both existing and non existing files.
