IE7 can't view cgm files on a UNIX server, but IE6 can. Why?

I use metaweb browser plug-in  to view web-cgm graphic files using IE6. Currently upgrading to IE7 and now can't view the files. If I copy files to a WinTel platform, both browsers can see the graphics. I still need to use the UNIX box for a few more months before moving to WinTel. Any ideas as to why this is suddenly a issue.
Thanks

Metaweb is the graphic viewer used by our customer. Ti-Author (the tool used to build the graphics) and Metaweb have been tuned to each other. OpenOffice and Dia 0.97 are not options. We are currently converting to the WinTel platform from UNIX so the issue will be OBE in about two months. Still need to get through these next two months.

Thanks for the help

Downgrade to IE6 for two months. Acyally not IE7 killed it, but ActiveX killbits update.
Alternatively - get supported metaweb release so that it is not disabled by IE7

Found the solution! In IE7 you have to go to Internet Options, Security, Trusted sites, Sites. Because UNIX and Windows don't play the same way on the network. You have to add the UNIX server by name to the Trusted Sites without the http or https. Once this was done at each clients desktop the viewing of web cgm graphics was no longer a problem. Note, this works with IE8 as well and with Windows 7.

Thanks for your help.

MEtaweb upgrade to get around ActiveX killbits is more of a long-lived solution.
