Selecting filter value doesn't work

Hi guys,

I've a random problem on some bex query when I try to slect filter value on navigable info object of the query.

The problem is that I can't select filter value because of the message:

<b><Install error> Missing ActiveX component: Business Expolrer Selektor</b>

Have you never had this kind of problem? Somebody knows how i can solve it.

Thank you,

Marco
