From time to time I still get the lockups.
Harry, I will make the same suggestion to you as I made to Stan and that you might want to consider switching to the MySQL MariaDB instead of Access. I am not wise in the ways of database programming, but apparently this Maria thingy is a lot more efficient than Access for some reason. I first installed it when my PC was running Win8.1 and it made the switchover to Win10 with no issues.
Here is a video Mike made that explains the process. I did it and I don't have any lockup issues. It is not difficult, but there are a lot of steps that need to be followed precisely as described. While I still have zero respect for Mike as a businessman, he appears to know what he is talking about in this video: https://www.youtube.com/watch?v=C7f-RZOnmDs
