Thanks for all,

about threads: your question (if my program is multithread) turned on
a light bulb over my head, the problem was that I freed the same
object in two different threads... (main thread and "cadencer") and I
think that it should behave something like:

"
if assigned(MyObj) Then
  begin
    freeandnil(MyObj);
    MyObj.Destroy;
  end;
"

instead of:

"
if assigned(MyObj) Then
  freeandnil(MyObj);

if assigned(MyObj) Then
  MyObj.Destroy; //of course this was wrong anyway.
"
