CGI links broken in preview

System

iwserver: 5.5.2 Build 20638 Interwoven 20030604 on W2K.

I am previewing a templated page that contains links passing URL parameters to CGI scripts in the same workarea. When I view source of the page the links looks right, and if I paste those links into the same browser they work. But when I click on the link in the previewed content something apparently inserts garbage into the file name. For instance if my previewed content contains a link such as:

/cgi-bin/test/script.pl?p1=whatever&p2=whatever

when I click on this link it takes me to:

/cgi-bin/test/zz_tst_jwest_0_script.pl?p1=whatever&p2=whatever

where jwest is my username. IIS then apparently tries to execute this script and I get an error message that it does not exist.

If I generate the page the links work, it's only preview that has this bug.

There are no proxy rules here.

What is causing this? Is there any way to turn off the translation of my file names?

Apparently every link in previewed content gets translated into this zz_ rubish, then something on the back end removes it and this works for things other than Perl scripts. If Interwoven could provide an explanation...

Also, if I use href=javascript:window.location = whatever there is no problem, but that's pretty lame too.
