I'm soory that I couldn't answer your questions earlier. I was on the road for a project and had no time to visit the forum for two month.
I set IE to prompt for ActiveX controls. so when I display any page of the forum it tells me that an safe for scripting ActiveX control wants access. If I select NO I don't see any change in the display and function of the page. It is still annoying. I can use Firefox of course, but still there shouldn't be an ActiveX control called for the forum pages. I don't know what control is called. The page source code doesn't have an object tag.
