Want to catch pywintypes.api_error

[Franz GEIGER]

When I start win32api.FindFiles(filespec) with a non-existing filespec it
throws an exception of class pywintypes.api_error. But a "except
pywintypes.api_error, e:" does not work. Using "except Exception, e:" does
the job, because Exception is the base class. But how can I catch api_error?
What do I miss?

Thanks in advance and best regards
