Thanks Gerry. I don't see how the extra information adds anything
useful, but here it is:

Event Type:    Warning

Description:
The description for Event ID ( 0 ) in Source ( ImageMagick ) cannot be
found. The local computer may not have the necessary registry
information or message DLL files to display messages from a remote
computer. You may be able to use the /AUXSOURCE= flag to retrieve this
description; see Help and Support for details. The following
information is part of the event: UnableToOpenConfigureFile
`delegates.xml'.

My Canon Ixus 60 isn't new, but my PC is.

I also posted to the SysOpt forum and had the following reply. I don't
really follow it but it seems broadly reassuring! Still like to
properly understand and remove the Event Viewer warnings though ;-)

ImageMagick is both a stand-alone image compression tool and a module
within Drupal. Drupal is a quickly emgerging cms (content management
system) development package/application.
In it's stand-alone version, you may be browsing sites that utilize
ImageMagick for their delivery of content in an expedited manner
(richer/larger images utilizing less bandwidth).
In its module format, Drupal integrated it for the same purpose to
roll out, track, and manage content.
Either way, it's not something inherently dangerous. What you are most
likely seeing is a site that is trying to present compressed assets,
but someone forgot something in the operations....either not creating
the delegates.xml or setting the configuration to look in the correct
directory for that file. I wouldn't worry about it....unless you own
the site
