Summary: Strange exception handling in win32api registry fns
Initial Comment:
Hi,
The registry handling methods in win32api seem to have
problems with
the Python exception handling. It took me some time,
but I have
managed to isolate the problem to a simple program. But
the problem is
more severe in more complicated situations, and there
it seems to
happen with most (or all) registry methods
(win32api.Reg...()).
The methods of _winreg module do not exhibit this
problem. For now, I
am using _winreg. However, it would be nice if the
problem could be
tracked down inside the win32api's source code and be
fixed.
regards,
Hung Jung Lu

This has been fixed - my test_win32api module no longer
shows a stale exception.
Thanks!
