Failed to read Imagelist data from stream. Updated

Title: failed to read Imagelist data from stream. Updated.
Question: Exception EreadError in Module {RB2K4} at {00023B03}
Error reading {Inormal16.Bitmap}:
failed to read Imagelist data from stream.
Answer:
If you use a toolbar with an imagelist or an imagelist elsewhere you
could be in for an unpleasant surprise.
After compiling and run or directly via the Run command you could receive the
errormessage:
Exception EreadError in Module {RB2K4} at {00023B03}
Error reading {Inormal16.Bitmap}:
failed to read Imagelist data from stream.
The text {..} is depending on your project.
Repeatingly closing down Delphi and trying again to compile and run your
application will generally be successful.
Nevertheless a pain in the back
The problem is the compatibility of the different COMCTL32.DLL versions.
Updating XP with SP2 made for me the problem far worse.
For details see article 321841 on MS Knowledge Base.
MS states everywhere that the problem is solved in XP SP2, but forget it.
As said in XP+SP2 the problem is really a pain somewhere...
If you encounter this errormessage the solution is to recreate
the immagelist.
A second solution is to create a resource file for the bitmaps of the
imagelist and load them in your application at runtime.
That works and is maybe always the best approach to use imagelists
Look at DK3 article 526 from Igor Siticov .
I fear that - given the fact that the incompatibility was solved and
re-emerged more than once - the problem will return with each update
of MS Windows.
Via the comments in article "Themed Delphi IDE" I found that the problem
is for me was caused by a manifest in the Delphi6/bin directory.
The manifest forces the use of the latest COMCTL32.DLL
Without the manifest the previous version of COMCTL32.DLL is used.
With the release of Delphi 6 Borland made somewhere a remark about the
use of a manifest. After removing the manifest the problem disappeared.
It seems that this article is of no importance after all, but that
is not true.
Some people need the use the latest COMCTL32.DLL and for that the
manifest (e.g. for Theming).
