Thanks for looking at the enclosed project.
My Lazarus installation filename is: lazarus-1.6.0-fpc-3.0.0-win64.exe
Version #:1.6, 2016-02-14, FPC Version: 3.0.0, SVN Revision 51630,
x86_64-win64-win32/win64.
I observe the same behaviour on another W10-64 laptop PC, same OS,
same Lazarus.
I wonder what setting I have missed...
