Thomas:

I am not sure if this will help but we had had trouble in the past with
imagemaps on various unix servers (NCSA, Apache, Netscape, etc;) for a few
different reasons.
* the map file on POLY shapes contained lines that were too long (too many
defined points)
* the map file had DOS or MACINTOSH end of line characters instead of UNIX.

Both these things caused the problem you mention. With the POLY thing we
basically broke it up into two or three definitions keeping the line
lengths short. With the EOL character you can you use any decent editor to
change it to UNIX. Hope that helps.
