I see this issue has been resolved for one person in this thread but mine apears to be a little different.
I have XP Pro with all the latest updates and all IE8 addons are showing as enabled. For the last few weeks the green site safety browser protection indicators do not load up with Google. I can get them easily just by opening NIS' control panel and switching it off and on again. Not a big deal really, just annoying. No seetings have altered and I don't even have to close IE8 for them to re-appear. Surely I don't have to keep doing this everytime do I?
