Thanks again for taking time to help me! When you speak of the "AHP recycle bin," is that the "garbage can" at the lower left of the screen. Presuming so, yes, it's empty. However, of more significance is the so-far-successful response I'm getting from something I did during continuing troubleshooting in this end. We had solar panels installed in December of 2015, and I was provided with a "gateway" through which I could, by browsing a specific IP address, monitor the output from each panel in real time. I had forgotten that item during my process of disconnecting things to try to isolate the problem. Doing so has, over the last couple days anyway, left me with smoothly-running "Before" and "After" macros! Hopefully, this will continue. If so, I'll try reconnecting the gateway using a line filter, and see if it can still get whatever information it needs through it, while allowing continuing macro smooth performance. Frankly, the macros are more important, from a personal satisfaction level!
Even though the specific apparent-resolution wasn't explicitly suggested, I don't think I would have stumbled on it were it not for the helpful ideas coming from you two community members. You kept me focused of the effort. So, again, thank you!
