Thank you for your post.
Using FileMaker Pro Advanced 15.0.1 under Mac OS X 10.11.5, I am unable to replicate the issue. I have tried several different files; some new, and some as old as FileMaker Pro 7.
Does this spacing occur for every field on the layout? If so, does this spacing occur for all layouts? If you create a new database file with one text field, are you able to replicate the spacing issue? I'm trying to determine if it is a field issue, a layout issue or a file issue.
To be perfectly candid with you, I can't say that I will be able to answer these questions any time soon. I am scrambling to finish a number of projects this week before going out of town for a week, but I will keep an eye out for other places where the same thing might occur.
For now, I have only seen it in one database, on one layout, in 2 fields.
I seldom use the "Condensed" text style, so testing this in other databases, other layouts, etc. may take some more time and effort than I have right now. I just wanted to be prompt about reporting it today.
Unless others report the same thing, you could consider it unimportant. One thing I hesitate to do in reporting it, however, is to use the word "Style" since it has a new meaning in the Inspector and I don't want to mislead you.
