My IE security settings reject it (and all ActiveX controls) of course, but I'm curious — what ActiveX control is this site (and Server Fault) trying to run?
Note: It doesn't always happen. Something connected to the ads perhaps?
Probably throwing a hissy fit because of high security settings triggered by the inclusion of jQuery.
We don't use any ActiveX controls, can you clarify what it is you're referring to?
EDIT: we have looked ad this and we have no idea what IE7 "thinks" it is blocking. Any ideas?
