No, as I said, I have not updated yet because it will necessitate spending about $600 in specialized software for my other job that I have not been able to spend due to several surgeries we have had to have. My cousin is the director of the computer lab at a local university and he told me I could wait a little longer, and he will come down here and help me when I do upgrade just to be on standby for any problems. But no, I have not upgraded. And I have had no problems with any of my software or subscriptions until now.
Properties are all the same. There seems to be no rhyme or reason. The PhotoShows that were deleted were actually much smaller in volume than some that saved without a problem, too.
