He recently found a problem in WinPT concerning the way it
communicates with GPG to handle smart card (edit) functions.

In all prior versions to 0.9.90 (final) it is possible that
WinPT indicated the PIN was successfully changed but actually
the old PIN is still in use. If a mailer caches the PIN and sent
the (invalid) PIN to GPG multiple times, the card will block.

The problem does not occur if WinPT is used to sign or decrypt
data protected with a key that is located on a smart card!

I released a new version of WinPT (0.9.90 final) which fixes this
and some other smart card related problems. The new version is
available at
