Hi Ian,
Check to see if you are publishing your Visio 2002 drawing on a Unix-based
Web server. If so, you will want to review the information in the following
MS Knowledgebase article:
VISO2002: Considerations When Publishing to UNIX-Based Web
Servershttp://support.microsoft.com/default.aspx?scid=kb;en-us;810624&Produc
t=vso2002
Also, if you are using the Visio 2002 Save as Web Page feature to publish
your drawing as a web page using the default VML output option, and you are
publishing to a Unix-based web server, you will want to update the filenames
of output files. You can do one of two things:
1) Edit each <filename>_vml_X.htm file (X is the page index) and change
<filename>_vml_X.emz to <filename>_vml_X.EMZ.
OR
2) Rename each of the <filename>_vml_X.EMZ files to <filename>_vml_X.emz.
I hope this helps.
