event with mshtml.HTMLDocument

[yex]

I get the following error with

Private WithEvents doc As mshtml.HTMLDocument
Private Sub doc_onmouseover() Handles doc.onmouseover
'mycode
end sub

Error:
'onmouseover' is ambiguous across the inherited interfaces 'mshtml.DispHTMLDocument' and 'mshtml.HTMLDocumentEvents_Event'

What can I do ? Should I remove Handler ?
