IE doesn''t seems to respond to the observe_field properly for me. I''ve tried different frequency settings, 0.5 even down to 0.05, but it takes lliterally seconds for IE to respond. Is this a known problem? This is on IE 6 on the pc, and it doesn''t work at all in IE on OS X on a Mac. It works fine in Firefox on both platforms, and Safari on the Mac. Thanks, Rob
