GetActiveOleObject fails even though CreateOleObject succeeds

Can some one explain what I am doing wrong?  After I successfully open
IE from Lazarus, then I try to access it again later in code, I will
get a "RPC server unavailable" error message.  In an attempt to
overcome that error, I decided to try and "find" the Ole object by
using GetActiveOleObject().  But that fails too... even immediately
after the successful creation of the Ole object.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  uses  ...
Windows, ComObj;...Browser :=
CreateOleObject('InternetExplorer.Application');  // <--- this line
succeedsBrowser := GetActiveOleObject('InternetExplorer.Application');
 // <--- this line fails...  
Error displayed:
Operation unavailable.

hello,
may be a problem with the internet explorer com object. 
With ms Word i have no problem with this code :
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.Button3Click(Sender: TObject);var msWord,sourDoc :
OleVariant;beginmsWord := CreateOleObject('Word.Application');msWord
:= GetActiveOleObject('Word.Application');sourDoc :=
msWord.Documents.Open('d:\temp\monDoc.doc');msWord.Visible :=
true;end;maybe it is time to use other thing that internet explorer
(end of life).  See this message

Friendly, J.P

No problem, this is a precaution taken for security reasons.
You cannot connect to a session opened in Internet Explorer for
security reasons, you can only access the session you started.
