In WSocket.pas, XSocketDeallocateHWnd, there should be a call to
SetWindowLong().
function XSocketDeallocateHWnd(Wnd: HWND): boolean;
begin
SetWindowLong(Wnd, 0, 0); { Clear the object reference }
Result := DestroyWindow(Wnd);
end;
If not, make sure that you have latest ICS-Beta installed (not
sure if it is in the release). I've my doubts that order of
destroying the windows matters, but not 100% sure.
