You still fully duplicate the logic. You really didn't get anything I said, did you? Please as to go back to square 1 and read again. So take a step back and try and explain what and why you're doing things, also try and look at what other people are doing. If I see another patch from you within two weeks I'll simply delete it, there's no way you can read up and fix everything in such a short time. --gK07V1xo3z7kEGDf Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJTjb8WAAoJEHZH4aRLwOS6oOsQAKI26ZCB9FRgjaYeVHLoa0+z iap1EvqblYx19ew9ph7mzJlLHwUCcPWaD9ZiSzSYDnhFfZ7TR8mqfvDyzGnFkIbD zpGVoKZRG22NerM9udYrsuNZihXo8WqMh5FbtX3baGoLDWgdIKOb/e+LQhaiy1Gq WJJNwhjKEYT5tzNvTWXPd8sTKbL9Nvb6r7xhSUGBnBXDbRxa3Q5vryk2+nrDqgwr KvalXbVH9Jm/HB6VVUHa6r/V6Q/LJfz8BkW9UqC9kgXXfQhYl+OmADLQC8UMGJcH tH/O/scwJDBtCyj0SUSDbGrT8/mHpf6SpSah3kWvm75WR9FhKJpkxjbb1wOIq5OD neMmV4sUT0wjtdP+XXAb1Tfr2iMUu4TegIwl752tplO5fJpey0sjnklXAu7mnaSM TqQ5TZGZVbWgwxv0E7PTaEoQsKHdRw1SECL0KN8cweSzDWGn8XdWcX3+U/seKgF2 uo0P/ZhdoP+rmNbAsEi8OHpb1OkFGIrZZIQILzSIa2Yq6lvFtRfYBVyVDMK3834A 36rEY1+PqkNwZ1BPmpcw4Sl8SZ6lBBDTZroBe3UXF522t9OiBqWg9LELjPJVqotW HevL2Mf+k8yGIJOW1KB5i95QZFa+XSdD6PYGfFPrFVt1Jr7iXGjFwbm8Flyikr22 qT+gEZLw59s1AU6Zy+07 =FJAB -----END PGP SIGNATURE----- --gK07V1xo3z7kEGDf--
