Thanks for the help. I’ll try all those things, but I suspect the problem is something else.
What I’m talking about happens before any of the coding should have any effect. I’m just inserting an image into the post in the “Add New Post” window.
The problem seems to be related to the way the cursor and text jumps around in WordPress in general. This actually has been driving me a bit crazy. What I mean is that I put the cursor into the text window in the “Add New Post” window where I want my image to be. But the second I move the mouse pointer out of that text window to click on one of menu buttons (like the “Add an Image” button), the slider on the right side of the window zooms all the way to the top, and I can’t see where I put the cursor anymore. Then when I insert the image, it ends up at the top of the post. This is long before I publish or even save the post. So I don’t know that HTML or CSS or PHP coding could be having an effect yet.
This also occurs when I switch from the Visual window to the HTML window. I’ll see a problem in the layout in the Visual window. So I want to look at the code and tags there. So I switch over to HTML view, and I’m thrown to the top of the post again, and I have no idea where the problem is anymore. I have to scroll all the way back down looking for the code that might be causing the problem. It’s easy to spot in the Visual view, of course. But the cursor won’t stay where I put it when I switch to HTML view. It makes it very hard to pinpoint any problems.
In my searching around the Internet for a solution, I’ve come across lots of people talking about this same thing, and no one seems able to fix it. They just learn to live with it.
