Is your version of IE updated? The last security patch from Microsoft blocked Active X, so if you have that stuff on your site, anyone who uses XP's "automatic update" function (or anyone who manually updates their copy of IE regularly) will not see your buttons. Or whatever it is that's there.

Personally, I prefer "rinky-dink" web sites. Plain ol' HTML for me. Java, Flash, ActiveX, etc., are usually just annoying. If they actually do add functionality, fine, but to use them for the sake of using them drives me nuts. Heck, that's why I hang out here at Rosity. They keep Java, Flash, etc., to a minimum.
