I am new of this topic and i hope for help.
I use a Lazarus 1.6.4 with FPC 3.0.2 on a Linux Slackware 13 machine with my software from more time.
and it is all ok with F8 Ster over function
now, I made a simple change to the code, I set a specific print font.
now the code no longer works,
I checked the code with F8 Step by Step and I see that Lazarus skips lines of code that are the ones incriminated.
You could help me please
