OK, I dropped Haloscan/JS-Kit because it created a hit on loading time, and went back to blogger comments, which killed my old comments, and that could not do trackbacks,or edit my comments, which I do occasionally to correct my spelling.
Well, it appears that the removal of the old haloscan comments, and the reinstallation from JS-Kit, as opposed to the old Haloscan, restored everything, and eliminated the performance hit.
HTML magic of some kind, I guess, or perhaps it’s just because the JS-Kit folks were not upgrading the old Haloscan servers, or the hand-off between Haloscan and JS-Kit was slow, or maybe just some old code.
I don’t know, and I don’t care, but for now, at least, Haloscan is back, and so are all the old comments.
Sorry for any confusion.
