Because Create is a legal method call as well. You can call a constructor like a normal method on an existing instance. > As mentioned, I do not get the error at the .Create call, but at anything after that... > I do not have a working Delphi system at hand right now, but I am sure that this would have compiled and worked on anything up to Delphi 2006 just fine. Delphi will compile this (like FPC does), but it will fail at runtime. Trust me here, I did the mistake a few times myself when I thought about too many other things. Regards, Sven
