Hi all. Using the latest versions of siera andItunes, I am having a problem when I am in the store. I select it, then try to use command F to search. It doesn't seem to work. I either get the piano note, or if I hit just F, I am taken to the search box. But after I enter a name of an artist, I can not use Tab to go tothrough the page. Quick nav isn't enabled, I just checked. Has anyone had this problem? I don't know if I can fix it or how to fix it. Thanks.
