if it does!


- Repost follows:


Hi everyone,


Alexei M Reatov <✉mail.href.com> found a bug in OleCtrls causing
terrible memory leaks when working with the TWebBrowser-ActiveX component.


function TOleControl.GetIDispatchProp(Index: Integer): IDispatch;
var
  Temp: TVarData;
begin
  GetProperty(Index, Temp);
//  Result := IDispatch(Temp.VDispatch);       *****  Change to:
  Pointer(Result) := Temp.VDispatch;            *****  This avoids the extra
AddRef
end;


Same applies to GetIUnknownProp().


By decending the TWebBrowser object from the attached TOleControlFix, the
problem is solved in a packet-compatible way.


- End of repost
