I found the log file. I looked at the content and it said to delete the Flash.OCX file and reinstall PinballX. First, this Flash.ocx is like bubble gum on the sole of your shoe, it doesn't like to be removed, so I moved it to another folder. I reinstalled PinballX, but I kept my playfield data base and config file from my 2019 version, as I have several hours of work to build this correctly and if I have to do it again, it just would not be worth pursuing this. I digress, I restarted windows 10 and tried running pinballx, but it was behaving weird (I was missing all but two tables). I exited pinballx and obviously and predictably the mouse curser disappeared again. Reboot, same thing. My machine is broken, and the problem is caused by pinballx. Attached is my log.
