Hi Larry,

yeah I read that mark, but since I'm using this internal link and didn't had any trouble with it this and the last year, I thought off as obsolete or at least solved. My home town observatory uses a 24" Cassegrain telescope with 7460mm of focal length resulting in a field of view by 9arcmin without a shapley lense with will reduce the focal length to 4700mm. So we got for the somewhat fainter asteroids because we easily reach 21mag. As I'm checking what's new at neo's manually, too. I didn't had any trouble using the internal links to download an integrate the files without restarting guide9 which saves much time.
I couldn't find any lacks between the two versions because one is derived from the other.
At first, when there wasn't any build-in solution to get the target lists in guide format years ago, I wrote my own converter for different catalogue sources but since Bill  provided us with the most catalogues by default, I stoppt using my converters.

Again, we do make intensive use of guide/mpcorb since I got our Apogee CCD camera up and running again in the beginning of last year and we didn't had any trouble with finding any selected. displayed or in somewhat odd target.
Maybe it's related to the kind of usage since we don't use Windows anymore. We solved some other problems with the systemclock and the telescope pointing by that, too.
