I think Brian put up a post on how to configure the keyboard plugin.
For the screen editor, you cannot align controls that are in separate containers. A container is a page, group box, or notebook page. A control on page 0 (Default) will always show up and it may appear that it occupies the same container. But appearances are just that, appearances. It is hard to catch things like that (read impossible) in the screen editor because we can't tell that you didn't mean to do that!!! Because it is perfectly acceptable in some circumstances. Look at the tree on the left to tell where a control is actually placed. It will have a parent. That is a good way to figure out if an accident happened.
Making a copy of the screen set before you edit it is a good idea.
