That's what I hoped for. If I regasm /tlb mycomponent.dll on my dev
machine, and reference it with <object like I initially mentioned, I
still get the "unsafe activex" component. But guess I can dig into the
IE functions and just allow it all.

If you want I can post my code and settings to see if I'm doing
something wrong.

If I change the security settings for my IE instance, will this affect
the other IE's the user might have running?
