Problem with Delphi 2006 Indy that is NOT in Kyix/Indy

I am in the process of porting my code form the now defunct Kylix
(Professional Version 3) compliers to Delphi 2006. Under both I am using the
versions of Indy that came with them. With the Kylix version I can correctly
decode every attachment that we see in our typical case, with the Delphi
2006 (Enterprise version) Indy I can not decode a specific case, here is the
email source from the case in question...

Here is the code that I am using which is identical on both systems (a
literal copy/paste)


----BEGIN CODE SNIPET----
For LCV := 0 To AMsg.MessageParts.Count-1 Do
    Begin
     LastToList.Add(AMSG.Recipients.Items[0].Address);
     If (AMsg.MessageParts.Items[LCV] is TidText) Then
     Begin
       LastBody := LastBody +
(TidText(AMsg.MessageParts.Items[LCV]).Body.Text);
     End
    Else If (AMsg.MessageParts.Items[LCV] is TidAttachment) Then
     Begin
       If FileExists('tmp.tst') Then DeleteFile('tmp.tst'); //save wont
overright or apend
       TidAttachment(AMsg.MessageParts.Items[LCV]).SaveToFile('tmp.tst');
       FileStrings.LoadFromFile('tmp.tst'); //kills entries in the string
       LastAttach := LastAttach + FileStrings.Text;
     End
    End;
----END CODE SNIPET----


Any ideas ?

Thanks!
