Remaining Issues

22. August 2009

There is an issue left with D2010:
The interface IXMLElement is no more available in file msxml.pas (MS XML Version 1). So the file JwaUrlMon.pas has been changed to use a Pointer instead of the IXMLElement interface. Unfortunately, the new IXmlDOMElement (MS XML Version 2) is not compatible with the old interface.
If you have an idea how to fix that, please mail to us.
