You code is wrong, it also crashes with kylix.What kind of answer is this?
The correct one?
To remove an item from a TList you must:
(a) set it to nil and pack the list
e.g.
list[0] := nil; list.pack;
(b) call TList.Delete(index)
e.g.
list.delete(0);
(c) use TList.Remove(pointer)
e.g.
list.remove(t);
Did the explanation not make sense? You obviusly do not understand how pointers wor... right? A pointer points to a memory address. Setting a pointer to nil, does not remove that block of memory from existance... for example:
var a, b: TObject; begin a := TObject.Create; b := a; //b points at a freeandnil(a); //at this point, b still points to the memory allocated to a, but this memory is no longer valid, and it will A/V if you free b
b.free; //access violation... end;
Do you understand now?

that should read:
..
begin
a := TObject.Create; // a points to a newly created object
b := a; // b now points to the same object (that is already pointed to by a)
..
