YES! I just asked Xp-software about the very same subject. It is maddening. Every time we upgrade the results totally change. I would like to supply our client with a reasonable explanation for the drastic changes in results, but they were unable to provide one.
Sorry, I know this forum is not to dump on any particular software/software vender. But this is almost like a public service announcement.
