I often get revised versions of a record and make a duplicate and edit as needed.

In 13 my memo fields do not keep line structure
line 1
line 2

Instead they be come one big continuous string of text.
line 1 line 2 line3

At least a space is added before each line.

Is there a fix or is this just something we have to live with?

Of note I am using my office's Dell laptop that was just "upgraded" to Win8.1 why not 10 beats me... 7 was so much better that 8 or 8.1.
