I don't know the details of it - my understanding is that initial 3D coordinates work for many cases (though the ring system in Nicholas's example did not work for me) but geometry optimization does not work.

Correct - but if vector results have to be differentiated from scalar results, I don't see much way other than an instanceof check, or prior knowledge of the result type and a coercion. So if you're going to do an instanceof check, why not do 3 more :) - ------------------------------------------------------------------- Rajarshi Guha <[EMAIL PROTECTED]> GPG Fingerprint: D070 5427 CC5B 7938 929C DD13 66A1 922C 51E7 9E84 - ------------------------------------------------------------------- A mouse is an elephant built by the Japanese. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) iEYEARECAAYFAkg1AkYACgkQZqGSLFHnnoRrEQCeOyZ0ltjQJKeuJbpabpkRxbxV JhwAnRKClXxUBrhvaMEZeKjixcExYGBE =g5T4 -----END PGP SIGNATURE----- ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
