I've been digging into the code, but I'm not yet comfortable to seriously attempt this myself, certainly not without guidance. It's a shame TJ seems to have disappeared, it would have been great to have had a look at his code, I'm sure many of these problems would have been resolved. Any help, workarounds, guidance or patches welcome! :) --=-GR0nh7aZkJFPvz8ZbOn2 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iEYEABECAAYFAk+CvrMACgkQGcb56gMuC63ZNgCcCApjYqWft7eftL/XqqH2aFSV 19wAoKPbykGpRU8e/a7elgnZfgcjpZmG =pf3o -----END PGP SIGNATURE----- --=-GR0nh7aZkJFPvz8ZbOn2--
