In the General tab of the layout setup window, there are three check boxes. The bottom one is defaulted to be checked and does what it says - prevents delineation of records except for the current (active) one.
Uncheck the box and see what happens.
Also, the middle box does something you might like or not.
Thanks, that solved the problem. I checked the middle box “Show field frames when record is active” to see how it works. Interestingly, only some of the fields were framed, but not all. I wonder why not all?
Only fields that can be edited from the keyboard should show a change in appearance when you open the record for editing.
