Greg, I tried that (see my posting on 2/10 23:16) but it didn't help.

When I got my system 3-and-a-half years ago, I purged it of all the Microsoft software that came with it (except for Win95 and DirectX). I'm wondering if the ActiveX component is looking for some obscure file that I've never needed before? However, I'm not about to reinstall Windows to find out!

I expect that only the people who wrote the MXOP will be able to diagnose the problem. I sent HTM an e-mail about it, but haven't yet received a reply.
