This will be tolerable for now. At least I don't have to refresh 5 or 6 times before I can get enough of the fields to appear that I can post something.
This doesn't look very elegant, though, so I'll still be looking for another solution.
Wordpress has consistently given me grief every time I attempt to post. I don't know what the problem is, but it seems I cannot easily resolve it. I see no reason to continue torturing myself with it. This is an experiment.
