Do you have a URL? I looked, but wasn't able to find anything. I'm
assuming
also that the inablity of iframe to display items in a folder in the
file
system is related to the same issue? When src in a iframe is set to
C:\Documents and Settings\holled\My Documents, the iframe will only
display
the contents if it is NOT hosted in Outlook. When its hosted in Outlook,
the
contents are displayed in a new window.
