well it's not 9 , not 8, i think it's 7 i'm not so much in Windows, so i can tell but when i checked my yahoo mails today and clicked on upgrade your browser it takes me too IE8, so anyway it's an old version, and i didn't care too much because i'm using mozilla,anyway on this IE on the site Internet Explorer cannot open the site.Operation aborted, anyway i don't think it's a problem i wonder how many of us still using older version of these things,anyway i cannot install a new version of IE because of my antivirus Deep Freeze -after one session deletes all cookies , all updates and comes back to initial state after the first reboot.so all my casinos aren't on my usual internet pc , i kept them on another one, so prevent addiction.Lol
