Thank you. Now that I’ve come to see just how bad an idea it was of my mine to attempt to use databases in local HTML pages, I will give that new preference you provided a try. It may be just what I needed. I appreciate your help.
Sometimes I should, perhaps, stop and think that if what I think I’d like to have isn’t available, there might be a good reason for it ; and I better rethink my approach. I tend to learn my lessons the hard way.
I’m pretty sure that I tried this before, when you suggested it in a different question of mine concerning iframes and the parent page in same-origin local HTML files no longer being able to communicate, and it didn’t permit it; but the old preference did. I will have to try again and see if it works in this situation.
