TOPIC:

Field1.Font.Style := [fsUnderline];

I accidentally left out the  Field1.  in the above code, putting in just  Font.Style := [fsUnderline]; .  There was no diagnostic message and the instruction caused the wrong field to be underlined.

Please, a project for our tests

I need to look at this some more.  Actually, even when I put the field name ahead of the ".Font.Style := [fsUnderline];", it still underlined some other wrong labels.  If I can find time, I'll look further.
