The AllocHWnd function failes after a number of calls.  It keeps
appending the AppDomain.CurrentDomain.GetHashCode to the end the
UtilWindowClass.lpszClassName.  After about 100 calls the ClassName is
Greater then 256 bytes.  This causes windows to not create the new
window handle.

This is a serious bug, affecting TTimer,
TPopupMenu

 and TListView Drop and drag (see QC report  21448 and
http://groups.google.com/group/borland.public.delphi.vcl.components.using.dotnet/browse_thread/thread/90edeadb66f952b7/0f687543b552b91a#0f687543b552b91a).

 I am sure there are other components that use this call!!!

This has been reported to Borland Qaulity Central report number 21771

Thanks
