Many thanks for your answer. I was unaware till yesterday of that DEP
(Data Execution Protection) thing. In fact, I have verified now that
for my OS, Windows XP 64 Pro, the default is having DEP only for
system sensible programs and services. In fact, in my machine my old
code from Delphi works perfectly. Therefore, I think that the obstacle
lies in my own code (most probable), in Lazarus or in FPC compiler.
This said, I have verified, to my surprise, that if I enable DEP for
all programs, my code raises an AV and stops dead. Therefore I am
deeply troubled about the future of my programas because I have two
problems, that of DEP and that of 64 bits code.
