>I'm having this Error message at home constantly. I have IE 5.0 at home. I don't have the same error at work, where I have IE 5.5 I believe, the problem is in older version of the Browser. I'm still reluctant to upgrade, because I need to download a huge file first, then what if it would not work, etc., etc.

We applied a fix over the weekend for viewing message. That was done Saturday afternoon. Did you experience it after? AFAIK, this specific one is resolved now.
