Hey folks.
At least I got an informed response.  See below :-

Good Afternoon,

Unfortunately the Macintosh Operating System does not support Map Viewer
presently.

The Image Web Server used in Map Viewer is propriety software from ER
Mapper (contact 9388-2900 or http://www.ermapper.com/) and is currently
only compatible with IBM PC's and Internet  Explorer 5.0 and 5.5 browsers.
ER Mapper do intend to make their software compatible with all operating
systems/browsers.

The Image Web Server plug-in for MacOSX will require Mozilla 1.4 or
Netscape 7.1 and above. It is not possible to support I.E or Safari on the
Mac as neither of these browsers support scriptable plug-ins.

If you wish to test the plug-in (it still has a few bugs) as it is now you
can go to...
http://www.earthetc.com/rightwebmap/rightwebmap.htm

The Mac plug-in will be part of the Image Web Server 2.0 release.

The Version 2.0 of Image Web Server will be released by ER Mapper sometime
in the first quarter of next year.
