Quote - It occurs to me that the reason I sometimes have this "conflict" problem with MS Outlook is probably because someone sends me an email with embedded Internet content, and this invokes web browser components, and among those is whatever Poser also wants but is not able to get (maybe one of these Flash*.ocx files).

My theory is that as Outlook very likely uses the IE core for rendering HTML content, it hooks or proxies in some protection which unfortunately affects other instances in other programs using the same core components.
