Thank you for the prompt reply. I'm afraid it did not solve the issue. But I just had the thought that perhaps what I'm wanting isn't possible any more. I want the enter key to take me to the very next line every time I key it, whether I am making a list or even typing a paragraph. This is probably due to the fact that I learned to type before there was such a thing as a text editor and I don't wait for the app to wrap to the next line. I want this behavior to just be the default for whenever I hit the enter key no matter what kind of document or text I am using. Now, I know this was possible because previous versions of Word allowed me to specify this as the default. I can force it to happen by hitting Ctrl+Enter at each place I want to start a new line, but I shouldn't have to do that. Right now, that's the only thing that works.
I can use the method you showed in your reply, or I can simply select the text and right click on it and go to the paragraph settings and make the changes there. It's a different way to get to the same place and there are probably other routes to that same setting. The problem is that the settings are not saving or otherwise taking effect. I'll make the change, then go back to writing and see the change isn't happening. I'll then go back to change it again and the settings are back to default. It doesn't matter where I make the change, the change doesn't happen. I suspect there is an issue which requires a repair of the office installation, but I'm unable to do that either. I explained that in my original post.
Am I left with having no other recourse but to uninstall Office and then reinstalling it? Is there a way to get a totally complete uninstall followed by a new clean installation?
