It always highlights where the cursor is, so you will always see one contact.

Thanks for the reply.

If that's true, than once again a software "improvement" makes things worse.

In my case, the cursor isn't on a contact, it is in the vertical scroll bar. No contacts were/are clicked/selected. I also noticed that if I delete a selected contact, then the address list does scroll up and down without a contact's details displayed, taking up half the window.

on the list part of the window there is a list looking icon on the right of the search box select it and change the "view" in the last entry to vertical layout, I assume you are using horizontal. It drove me crazy in less than a minute.

Matt - that helps, thanks (the contact details still pop up and take half the screen, but I still get the full vertical space for the list of contacts).

Also, I just discovered that if I use the mouse wheel to scroll, rather than clicking on the slider and dragging it up and down, then the detail window doesn't pop up.
