Is there something I can do to help fixing it before final 6.15 is out? --=20 Best Regards, Marek Marczykowski-G=C3=B3recki Invisible Things Lab --0nQ5TDnVhV5gn1bQ Content-Type: application/pgp-signature; name=signature.asc -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEhrpukzGPukRmQqkK24/THMrX1ywFAmgJ+sIACgkQ24/THMrX 1yzQtwf/V1Kwj5a1YqzIurMPiJsNiEryIIzzNggnyRm78T9GwN33DU6aKpvdbcwH q4Iz18yFSH2T8suYaXLjan3o4HkwIh6shkMRJ1S+J8KRP1vinn9Olq0pDu7bCxrl 98+lRYOQpl7n1s8Ne2Mw/z2aaUuE4rd2lKym9YrkkPhvijC7A3XeUqRSS8mkdydw gkx4Up1lc0hp0X1o90fc7UJYaxM231XjnT+HqVEYNsnt/8bsaj2FN09SJwsBmVTk 481dT17Ts2ffRRAw+4lp6ecY3Y+RIbKkvC0rra+y5XFaFzd6O7hQ9MrKxqkLH4xK WyLBwwfno2qFjv2Y2lzONmiSwS2YGw== =x2tm -----END PGP SIGNATURE----- --0nQ5TDnVhV5gn1bQ--
