Glad you asked. I think you and Wolfram both will be interested in this story.
Like most people I use an uninterruptable power supply (UPS) for battery back up and surge protection. The Mfg is APC and the model number is BVN650M1. Now, you ask, why should I care? Read on.
Attached are two notebooks. I presume you have the original graphic from my post as I had to remove it from the notebook to meet size limitations on this post. I was working on the first one, fabric1.nb, when my UPS emitted the telltale failure whistle and began blinking signaling a battery failure. I recognized this sound as I had only replaced it 60 days ago. Naturally I wanted to know what my warranty was. I shut everything down, contacted APC and they walked me through some in-place testing, concluded it was a battery failure, asked for and received a copy of my receipt dated in January and a new one is on its way as I type this. Because I have an entire separate computer system running Linux that is back-up for my Windows system, I was able to "borrow" its UPS for my Windows box and continue working.
Of course I went back to fabric1.nb, taking up where I left off. I evaluated fabric1.nb and WHAT DO YOU THINK HAPPENED??????????????????? YOU GUESSED IT - THE SECOND UPS BLEW UP. I hit Abort in the Mathematica menu and the whistle stopped. I evaluated the cell and it started again. I aborted and it stopped. I shut down the kernel and opened a new file (attached) as fabric2.nb wherein I tried putting Gridlines on top of the image to identify the corners. Not a great strategy, I know. Time consuming and tedious, the night got late and I put it aside.
So, I now have two questions...

Hi Roger,
Could you please share the notebook of your trials with us?
