Welcome to WebmasterWorld Guest from 22.214.171.124
I've tried the clearing the cookies, TIFS, history etc., adjusting the security settings, even tried repairing IE but nothing seems to fix it. The weird thing is that it corrects itself occasionally (without my doing anything) and all returns to normal for a while, then suddenly it happens again.
Curiouser and curiouser.
1 . Empty cookies
2 . Download and run "Hijack this". Maybe your browser has been hijacked by BHO exploits or like. Remove any thing that u find suspicious.
3 . It may also happen if u recently installed a Firewall/AV that is blocking scripts etc.
If none of the above solves your problem, download firefox and use it to log on to adsense CP. I think firefox is about 5 Mb or so.
Hope you fix your problem
