I’ve a VB.Net program that creates an xml document from a .net dataset. This xml document is showed in a web browser (IE 6.0 SP1) and I can work with the application without any problem, but if I left the application around 15 minutes (or more) and then I come back to the tool, I get the following error (trying to execute the .loadXML sentence):

QueryInterface for interface MSXML.IXMLDOMDocument failed

Where the xml document is defined as:

Dim m_objXmlDoc As New MSXML.DOMDocument()
m_objXmlDoc.loadXML(m_dsDataset.GetXml)

How can I fix this problem???
